Its lifetime is measured by a stationary observer in the laboratory to be seconds. What is the lifetime of the particle, measured in the rest frame of the particle? (Use m/s for the speed of light.) 32) A spacecraft is measured by an observer on the ground to have a length of 53 m as it flies overhead with a speed m/s. The spacecraft then lands and its length is again measured by the observer on the ground, this time while the spacecraft is at rest relative to him. What result does he now get for the length? (Use m/s for the speed of light.) 33) An experimenter is observing the inelastic collision of two rather rapid objects in order to test the predictions of relativistic momentum conservation. Particle A has a known rest mass of kg and moves with speed (in the lab) m/s. Particle B's mass is unknown, but it moves with speed (also in the lab) m/s. Initially the particles are moving in precisely opposite directions. After the collision (a near miss), the particles, to the experimenter's amazement, are each moving perpendicular to the original direction of motion. For this to happen, what must be the rest mass of particle B? (Like the experimenter, you should use m/s as the speed of light.) 31) 32) 33) 34) How much work must be done to accelerate a particle of mass kg (rest mass) from a speed of m/s to a speed of m/s? (Use c = m/s for the speed of light.) 35) Two spaceships are approaching one another, each at a speed of 0.68c relative to a stationary observer on Earth. What speed does an observer on one spaceship record for the other approaching spaceship? 34) 35) 36) As a rocket is moving past Earth, an Earthling measures its length to be 325 m, while the captain on board radios that her rocket s length is 1150 m. (a) How fast is the rocket moving relative to Earth? (b) What is the total energy of a 75.0-kg crewman as measured by (i) an observer at rest in the rocket and (ii) an observer at rest on Earth? 36) 7
