An observer in a rocket moves toward a mirror at speed v relative to the reference frame labeled by S in Figure P1.30. The mirror is stationary with respect to S. A light pulse emitted by the rocket travels toward the mirror and is reflected back to the rocket. The front of the rocket is a distance d from the mirror (as measured by observers in S) at the moment the light pulse leaves the rocket. What is the total travel time of the pulse as measured by observers in (a) the S frame and (b) the front of the rocket? Figure P1.30
You find yourself stuck in outer space with nothing but your physics book and a space suit. You have a mass of 91 kg in your suit, and your physics book has a mass of 2.3 kg. In order to make it back to your stationary spaceship before running out of air, you must move at 0.18 m/s. How fast (in m/s) do you have to throw your physics book to achieve this speed?
A 100-kg astronaut finds himself separated from his spaceship by 10 m and moving away from the spaceship at 0.1 m/s. To get back to the spaceship, he throws a 10-kg tool bag away from the spaceship at 5.0 m/s. How long will he take to return to the spaceship?
Mass of a Moving Particle The mass m of a particle moving at a velocity v is related to its rest mass m0 by the equation m = m0 1 − v2 c2 where c (2.98 ✕ 108 m/s) is the speed of light. Suppose an electron of rest mass 9.11 ✕ 10−31 kg is being accelerated in a particle accelerator. When its velocity is 2.87 ✕ 108 m/s and its acceleration is 2.45 ✕ 105 m/s2, how fast is the mass of the electron changing? (Enter your answer in scientific notation rounded to three significant figures.) ✕ 10kg/s

An astronaut with a mass of 75.8kg, finds herself 34.7m from her spaceship. The only way for her to return to the ship is to throw her 0.450kg wrench directly away from the ship. If she throws the wrench with a speed of 20.3m/s, how many seconds does it take her to reach the ship?
A car has a momentum of 15000 kgm/s. What momentum would the car have if it had thrice the mass and moving with one-half the speed?
an object in motion has a mass of 12kg and travels in the air with a velocity 0.82 what would be its rest mass?

A student says that a material particle must always move at a slower speed than the speed of light, and that a massless particle must always move at the same speed as the speed of light, both of which are incorrect. Is she correct in her assessment? If this is the case, how could massless particles such as photons and neutrinos achieve such a high rate of acceleration? Isn't it possible to start from a standing start and accelerate? Explain.
