Teenagers Sam and Tom are playing chicken in their rockets. As FIGURE Q36.2 shows, an experimenter on earth sees that each is traveling at as he approaches the other. Sam fires a laser beam toward Tom.
a. What is the speed of the laser beam relative to Sam?
b. What is the speed of the laser beam relative to Tom?
A rocket is fired from the earth to the moon at a speed of . Let two events be 鈥渞ocket leaves earth鈥� and 鈥渞ocket hits moon.鈥� a. In the earth鈥檚 reference frame, calculate 鈭唜, 鈭唗, and the space time interval s for these events.
b. In the rocket鈥檚 reference frame, calculate 鈭唜鈥�, 鈭唗鈥�, and the space time interval s鈥� for these events.
c. Repeat your calculations of part a if the rocket is replaced with a laser beam.
The nuclear reaction that powers the sun is the fusion of four protons into a helium nucleus. The process involves several steps, but the net reaction is simply . The mass of a proton, to four significant figures, is , and the mass of a helium nucleus is known to be .
a. How much energy is released in each fusion?
b. What fraction of the initial rest mass energy is this energy?
A 30-m-long rocket train car is traveling from Los Angeles to New York at 0.50c when a light at the center of the car flashes. When the light reaches the front of the car, it immediately rings a bell. Light reaching the back of the car immediately sounds a siren.
a. Are the bell and siren simultaneous events for a passenger seated in the car? If not, which occurs first and by how much time?
b. Are the bell and siren simultaneous events for a bicyclist waiting to cross the tracks? If not, which occurs first and by how much time?
