A truck covers 40.0 m in 9.45 s while uniformly slowing down to a final velocity of 2.10 m/s.(a) Find the truck's original speed._____ m/s(b) Find its acceleration._____ m/s2
(a)
In order to find the original speed, let's use the formula below to find an expression for the acceleration:
[tex]\begin{gathered} V=V_0+a\cdot t\\ \\ 2.1=V_0+a\cdot9.45\\ \\ a=\frac{2.1-V_0}{9.45} \end{gathered}[/tex]Now, we can use the following formula to find the initial speed:
[tex]\begin{gathered} \Delta S=V_0t+\frac{at^2}{2}\\ \\ 40=V_0\cdot9.45+\frac{\frac{(2.1-V_0)}{9.45}\cdot9.45^2}{2}\\ \\ 40=9.45V_0+4.725(2.1-V_0)\\ \\ 40=9.45V_0+9.9225-4.725V_0\\ \\ 4.725V_0=40-9.9225\\ \\ V_0=\frac{30.0775}{4.725}\\ \\ V_0=6.3656\text{ m/s} \end{gathered}[/tex](b)
Now, calculating the acceleration, we have:

Given data:
* The mass of the astronaut is m = 95 kg.
* The force read by the Newton scale when the shuttle takes off is F = 5500 N.
Solution:
According to Newton's second law, the force on the astronaut in terms of the acceleration and mass is,
[tex]\begin{gathered} F=\text{ma} \\ a=\frac{F}{m} \end{gathered}[/tex]Substituting the known values,
[tex]\begin{gathered} a=\frac{5500}{95} \\ a=57.9ms^{-2} \\ a\approx58ms^{-2} \end{gathered}[/tex]The shuttle and the astronaut are moving with the same acceleration.
Thus, the acceleration of the shuttle is 58 meters per second squared.

The press box at a basketball park is 38.0 ft above the ground.
A reporter in the press box looks at an angle of 15 degrees below the horizontal to see the second base.
Let us draw the diagram to better understand the problem.
Here x is the horizontal distance from the press box to the second base.
With respect to angle 15°, the opposite side is 38 ft and the adjacent side is x.
Recall from the trigonometric ratios,
[tex]\begin{gathered} \tan \theta=\frac{opposite}{adjacent} \\ \tan 15\degree=\frac{38}{x} \\ x=\frac{38}{\tan 15\degree} \\ x=141.8\; ft \end{gathered}[/tex]Therefore, the horizontal distance from the press box to the second base is 141.8 ft.
The speed of light in an unknown medium is measured to be 2.76 x10% m/s. What is the index of refraction of the medium?
Answer:
Explanation:
The formula for calculating the index of refraction is expressed as
n = c/v
where
n is the index of refraction
v is the speed of light in the medium
c is the speed of light in vacuum and its value is 3 x 10^8 m/s
From the information given,
v = 2.76 x 10^8 m/s
Thus,
n = 3 x 10^8 m/s/2.76 x 10^8 m/s
n = 1.09
the index of refraction of the medium is 1.09

(b) At what rate must you lift a 3.6-kg container of milk (one gallon) if the power output of your arm is to be 22 W? (C) How much time does it take to lift the milk container through a distance of 1.0 m at this rate?
Given,
The power consumed by a brain, P=22 W
The energy per bar, E=280 calories=280×4184=1171.52 kJ
The mass of a milk container, m=3.6 kg
The power output of the arm, P₀=22 W
The distance through which the container needs to be lifted, d=1.0 m
a)
The power is given by,
[tex]P=\frac{E}{t}[/tex]Where t is the time.
On substituting the known values in the above equation,
[tex]\begin{gathered} 22=\frac{1171.52\times10^3}{t} \\ \Rightarrow t=\frac{1171.52\times10^3}{22} \\ =53250\text{ s} \end{gathered}[/tex]That is,
[tex]\frac{53250}{3600}=14.79\text{ hr}[/tex]Therefore one snicker bar can power the brain for 14.79 hr
b)
The power output can also be calculated using the formula,
[tex]\begin{gathered} P=F\times v \\ =mg\times v \end{gathered}[/tex]Where F is the force applied by the container on the arm, v is the rate at which the container must be lifted, and g is the acceleration due to gravity.
On substituting the known values,
[tex]\begin{gathered} 22=3.6\times9.8\times v \\ v=\frac{22}{3.6\times9.8} \\ =0.62\text{ m/s} \end{gathered}[/tex]Thus the rate at which the milk container must be lifted is 0.62 m/s
c)
The rate at which the container must be lifted is given by,
[tex]v=\frac{d}{t}[/tex]Where t is the time it takes to lift the container at the calculated rate.
On substituting the known values,
[tex]\begin{gathered} 0.62=\frac{1}{t} \\ \Rightarrow t=\frac{1}{0.62} \\ =1.61\text{ s} \end{gathered}[/tex]Thus it takes 1.61 s to lift the container through 1 m at the given rate.

Heat can travel from one place to another in several ways. The different modes of the heat transfer include: Conduction, Convection, Radiation
Meanwhile, if the temperature difference exists between the two systems, heat will find a way to transfer from higher to the lower system.
Conduction is defined as:
The process of transmission of energy from one particle of the medium to another with the particles being in direct contact with a each other.
Following are the examples of the conduction:
Ironing of clothes is a example of conduction where the heat is conducted from the iron to the clothes.
Heat is transferred from hands to ice cube resulting in a melting of an ice cube when held in hands.
Convection is defined as the:
The movement of fluid molecules from higher temperature regions to lower temperature regions.
