The speed of car A after the collision is 0.52 m/s.

In everyday use and kinematics, the speed of object is the amount of change in position over time, or the amount of change in position per unit time. So it's a scalar quantity.

For a bumper car A

Mass (m₁) = 296 kg

Velocity (V₁) = 3.74 m/s,

For a bumper car B

Mass (m₂) = 222 kg

Velocity (V₂) = 1.85 m/s,

To calculate velocity of car A after the collision mathematically:

Vₙ =(m₁-m₂/m₁+m₂)V₁

Vₙ = Final velocity of car A

Vₙ = (296 - 222/296 + 222) × 3.74

Vₙ = 0.52 m/s

The resistance band's elasticity (stretchiness) dictates how easily it can be stretched or can be flexible.

It is the proportion of tensile stress to strain, where strain is the amount of deformation and tensile stress is the tension force applied to a surface area (amount of stretch of the resistance band).

Instead than requiring you to hold additional weight per se, resistance bands function by providing an external resistance force that can be imposed. They are flat, occasionally looping bands that might be thin or thick.

If I were a passenger in a convertible car traveling at a constant velocity and threw a ball straight up into the air, neglecting air resistance, the ball would follow a parabolic path and would eventually fall back into the car.

When the ball is thrown straight up, it will initially have a vertical velocity of 0 at the top of its trajectory. This means that it will begin to fall back down at the same speed that it was thrown up, due to the force of gravity. Since the car is moving at a constant velocity, the ball will appear to fall back into the car from the perspective of someone inside the car. However, from an outside perspective, the ball will be seen to fall to the ground at a point ahead of the car.

It's important to note that this scenario is based on the assumption that there is no air resistance. In the real world, air resistance would cause the ball to slow down as it moves through the air, which would affect the trajectory of the ball and would likely cause it to fall outside of the car.

"Saturn has the strongest magnetic field among all planets in our solar system," statement is incorrect.

A magnetic field, a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. When a charge moves through a magnetic field, a force that is perpendicular to both its own velocity and the magnetic field operates on it.

The magnetosphere, a massive magnetic bubble formed by forces deep inside Saturn, has a significant impact on the space environment close to the planet. Deep within the planet's fluid innards, material cycles produce Saturn's magnetic field.

The solar wind, or flow of electrically charged solar particles (electrons and ions), travels across the solar system at a million miles per hour beyond Saturn's magnetosphere. The magnetosphere of Saturn develops when the solar wind collides with its own magnetic field. The magnetic forces of the sun are strongest outside the planet's magnetosphere, while Saturn's magnetic fields are strongest inside the planet's protective envelope.

You must concentrate on the catch to win a water balloon contest without breaking the balloon. Momentum, impulse, force, and impact time are all important factors in the catch's success. The key to catching a water balloon without breaking it is to reduce the balloon's impact force. The momentum of the balloon, the impulse applied to the balloon, and the impact time all contribute to the impact force.

The product of an object's mass and velocity is its momentum. As it is thrown towards you, the water balloon has a certain mass and velocity. The greater the balloon's momentum, the more difficult it will be to catch it without breaking it.

In order to catch a water balloon, you must apply an impulse to the balloon. The higher the impulse, the more effectively you can stop the balloon.

The superconductivity is quenched when current through the wire causes the critical magnetic field at the wire surface.

Given that,

B = 0.2T

R = 0.001m (R = r/2)

a. Maximum current, critical current density

Ic = B*2πr / μo

Ic = {0.2 * 2 * (22/7) * (0.001/2)} / 4 * (22/7) * 10-7

Because light can come from an item in many different directions, a picture can be created. According to the rule of reflection, some of the light (which we depict as rays) hits the screen and reflected off of it.

Briefing:

For this exercise we will use the equation of the constructor

         1 / f = 1 / p + 1 / q

where f is the focal length of the salad bowl, p and q are the distance to the object and the image

The metal salad bowl behaves like a mirror, so its focal length is

Explanation:

Answer:

0.1667 meters/second.

Explanation:

To find Jibari's average velocity for the trip, we need to first calculate his average velocity for each leg of the trip. To do this, we need to divide the distance he traveled by the time it took him to travel that distance.

For the first leg of the trip, Jibari walked 40.0 meters east in 120.0 seconds. His average velocity for this leg of the trip is therefore 40.0 meters / 120.0 seconds = 0.3333 meters/second east.

For the second leg of the trip, Jibari walked 30.0 meters west in 60.0 seconds. His average velocity for this leg of the trip is therefore 30.0 meters / 60.0 seconds = 0.5000 meters/second west.

To find Jibari's average velocity for the entire trip, we need to add the velocities for each leg of the trip, taking into account their direction. Since the first leg of the trip was east and the second leg was west, we can simply add the two velocities together to find the overall average velocity.

Jibari's overall average velocity for the trip is therefore 0.3333 meters/second east + 0.5000 meters/second west = 0.1667 meters/second.

Therefore, Jibari's average velocity for the trip was 0.1667 meters/second.

Jibari's average velocity for the trip is 0.7 m/s east.

To solve for Jibari's average velocity, we will first need to find his total displacement. We can do this by adding the magnitudes of his eastward and westward displacements. The magnitude of Jibari's eastward displacement is 40.0 meters, and the magnitude of his westward displacement is 30.0 meters. So, his total displacement is

40.0 - 30.0 = 10.0 meters east.

We can then find Jibari's average velocity by dividing his total displacement by the total time it took him to complete the trip. The total time it took Jibari to complete the trip is

120.0 + 60.0 = 180.0 seconds.

So, his average velocity is

10.0 / 180.0 = 0.7 m/s east.
