a golf ball leaves the ground at a speed of 4.5 m/s and at an angle of 66.02 above the horizontal. what are the maximum height and flight time of the ball?
A golf ball leaves the ground at a speed of 4.5 m/s and at an angle of 66.02 above the horizontal.
Thus, maximum height of the ball = 1.534 m
the flight time = 0.839 sec
What is speed?The pace at which a distance changes over time is referred to as speed. It has a dimension of time-distance. As a result, the fundamental unit of time and the basic unit of distance are combined to form the SI unit of speed. Thus, the metre per second (m/s) is the SI unit of speed.
Given that,
Speed (u) = 4.5 m/sec
angle (θ) = 66.02
Flight time of the ball (T) = 2u sinθ/g
T = [2 ×4.5 × sin (66.02°)] /9.8
T = 0.839 sec
Range (R) = u cosθ × T
or, R = 4.5 × cos (66.02°) × 0.839

What are the uses of a pendulum?Pendulum a body that is hanged from a fixed location and moves back and forth as a result of gravity. Pendulums are employed to control clock movement because the period the amount of time between each full oscillation is constant.
Briefing:We will utilize the concept of the duration in a basic pendulum to tackle this issue, which cautions that it depends on the length and gravity of the pendulum:
T = 2π√(L/g)
Here,
L = Length
g = Acceleration due to gravity
T = √(L/g)
Since 2π is a constant, we can deduce that its proportionality towards the square root of the its lengths over its gravity is 2.
g→ 0 ⇒ T→∞
The object is in continuous free fall, or in a situation where gravity is typically zero.
The period's value will eventually approach infinity. As a result of the pendulum's attachment point also being in free fall, it means that the pendulum would no longer oscillate.

A sound of frequency 15Hz and an amplitude of 70dB is inaudible. This is true statement.
What is audible sound?The human ear can easily hear frequencies between 20 Hz and 20 kHz. Therefore, sound waves with a frequency between 20 Hz and 20 kHz are regarded as audible sound. The human ear may be able to pick up on even the smallest changes in air pressure if they are in the audible frequency range. The difference in air pressure is less than one billionth of a percent.

what is the change in potential energy of an energetic 64 kgkg hiker who makes it from the floor of death valley to the top of mt. whitney?
11,700 Joules are roughly lost from the hiker's energy stored. These are computed by adding the hiker's mass (64 kg), the elevation difference among both Death Valley & Mt. Whitney (2,400 m), and the lift force (9.8 m/s2).
Assessments must be made in the beginning to ascertain where far the climber is ascending. At 14,505 feet above sea level, Mount Whitney is indeed the tallest mountain there in continental United States. At 282 feet below sea level, Death Valley was its lowest place in North And south america. This indicates that the hiker is ascending an overall height of 14,787 feet.
Calculating the variation in potential electricity is produced following. Potentially energy is equivalent to something like an object's mass increases the speed caused by gravitation times the object's altitude. Therefore, the hiker's modification in energy potential can be measured:
(64 kg) * (9.8 m/s2) * (Change in Potential Energy) (14,787 ft)
9,424,912 kg/m2/s2 equals the change in potential energy.
The hiker weighing 64 kilograms will experience a 9,424,912 kg m2/s2 shift in potential energy as they ascend into the Death Valley floor towards the peak of Mt. Whitney.

Why is kinetic energy called the energy of motion?
Kinetic energy refers to a part of internal energy where immobility refers to potential and movement occurs with velocity as KE=mv²/2.
Kinetic energy depends on the velocity of an object and is the ability of a moving object to act on other objects when colliding with them. On the other hand, the kinetic energy of an object represents the amount of energy required to increase the velocity of the object from rest (v = 0) to its terminal velocity. Kinetic energy is a numerical measure of the inertia of an object and is also linearly related to mass, a measure of the object's resistance to acceleration when a force is applied.For a body of revolution, the moment of inertia I corresponds to mass and the angular velocity (ω) corresponds to linear or translational velocity. Therefore, the kinetic energy of rotation is equal to half the product of the moment of inertia and the square of the angular velocity.The total kinetic energy of an object or system equals the sum of the kinetic energies resulting from all kinds of motion.To understand more about Kinetic energy -

an object has an acceleration of 15.7 m/s/s. if the mass of the object is increased by a factor of 13.6, what would be the new acceleration of the object?
If an object's mass is raised by a factor of 13.6, its acceleration would change to 213.52 m/s from its initial acceleration of 15.7 m/s. For an object's mass gets increased.
In mechanics, acceleration is the rate at which an object's velocity with respect to time changes. The vector quantity of accelerations (in that they have magnitude and direction). The direction of the net force imposed on an object determines its acceleration in relation to that force. A physical body's mass is its total amount of matter. Inertia of the body is also measured by it.
F = ma
F = m*15.7\sF = 15.7m
The new acceleration is given by F = (13.6m*a) F = (13.6m*15.7) F = 213.52m where F = (13.6m*a)
