Chapter S2, Problem 45EAP
Relative Motion Practice II. In all the following, assume that you and your friends are in free-float reference frames.
- Carol is going away from you at 75 km/hr, and Sam is going away from you in the opposite direction at 90 km/hr. According to Carol, how fast is Sam going?
- Consider again the situation in part a. Suppose you throw a baseball in Sam’s direction at a speed of 120 km/hr. What does Sam see the ball doing? What does Carol see the ball doing?
- Cameron is traveling toward you at 99.9999% of the
speed of light when he turns on a flashlight and points it in your direction. How fast will the beam of light be going when it reaches you?

1. Two atomic clocks are synchronized. One is placed on a satellite, which orbits around the earth
at high speed for a whole year. The other is placed in a lab and remains at rest, with respect to
the earth. You may assume that both clocks can measure time accurately to many significant
digits.
a. Will the two clocks still be synchronized after one year? Explain your reasoning.
b. Imagine that the speed of light was much slower than its actual value. How would the results
of this experiment change if the speed of light was only twice the average speed of the
satellite? Explain your reasoning, using a calculation.
1. make me one question on relative motion in the forum with complete solutions.
here is my example below of what I am expecting you to answer:
NOTE: Don't copy the question below make me a similar question and solve that
1.A conductor in a train travelling at 4.0 m/s (N) walks across the train at 1.2 m/s
(E) to validate a ticket. If the trian car is 4.0m wide, how long does it take the
conductor to reach the other side?
vog=?
vom= 1.2 m/s(E)
(1.2/4.2)
vmg= 4.0 m/s(N)
vog=4.2m/s(N17E)
Ad
At =
Δυ
At = 3.3s
4.0m/s
1.2m/s
vog=vom+vmg
=1.2m/s(E) + 4.0m/s(N)
=sqrt (1.2m/s)^2 + (4.0m/s)^2
=4.2 m/s
