Chapter 36: Q. 76 (page 1062)

A ball of mass m traveling at a speed of 0.80c has a perfectly inelastic collision with an identical ball at rest. If Newtonian physics were correct for these speeds, momentum conservation would tell us that a ball of mass 2m departs the collision with a speed of 0.40c. Let鈥檚 do a relativistic collision analysis to determine the mass and speed of the ball after the collision.

a. What is gp, written as a fraction like a/b?

b. What is the initial total momentum? Give your answer as a fraction times mc. c. What is the initial total energy? Give your answer as a fraction times mc2 . Don鈥檛 forget that there are two balls.

d. Because energy can be transformed into mass, and vice versa, you cannot assume that the final mass is 2m. Instead, let the final state of the system be an unknown mass M traveling at the unknown speed uf. You have two conservation laws. Find M and uf.

At what speed, as a fraction of c,does a moving clock tick at half the rate of an identical clock at rest?

Let鈥檚 examine whether or not the law of conservation of momentum is true in all reference frames if we use the Newtonian definition of momentum: px=mux. Consider an object A of mass 3m at rest in reference frame S. Object A explodes into two pieces: object B, of mass m, that is shot to the left at a speed of c/2 and object C, of mass 2m, that, to conserve momentum, is shot to the right at a speed of c/4. Suppose this explosion is observed in reference frame S鈥� that is moving to the right at half the speed of light.

a. Use the Lorentz velocity transformation to find the velocity and the Newtonian momentum of A in S鈥�.

b. Use the Lorentz velocity transformation to find the velocities and the Newtonian momenta of B and C in S鈥�.

c. What is the total final momentum in S鈥�?

d. Newtonian momentum was conserved in frame S. Is it conserved in frame S鈥�?

FIGURE Q36.5 shows Peggy standing at the center of her railroad car as it passes Ryan on the ground. Firecrackers attached to the ends of the car explode. A short time later, the flashes from the two explosions arrive at Peggy at the same time.

a. Were the explosions simultaneous in Peggy鈥檚 reference frame? If not, which exploded first? Explain.

b. Were the explosions simultaneous in Ryan鈥檚 reference frame?
