Textbook Question
Chapter S2, Problem 50EAP
Time Dilation.
- A student, after learning about the theory of relativity, decides to try to prolong his life by spending the rest of his life traveling in a car at 55 miles per hour (89 km/hr). If he does this while 70 years pass in his house, how much time will pass in the car? (Hint: If you are unable to find a difference, be sure to explain why.)
- A more clever student decides to prolong her life by cruising among the stars at a speed of 0.95c. How much time will pass on her spacecraft during a period in which 70 years pass on Earth? Will she feel as if her life span has been extended? Explain.
- Suppose you stay home on Earth while your twin sister takes a trip to a distant star and back in a spaceship that travels at 99% of the
speed of light . If both of you are 25 years old when she leaves and you are 45 years old when she returns, how old is your sister when she gets back?

A severely injured Peter can only live for the next 3.5 hours. Before dying, he wants to go back to Earth which is 5 light-hours away. What should be the minimum cruise speed of the Peter's spaceship so that at least he can make it before he runs out of time?
HINT: The answer is NOT 4.29x108 m/s.
The fastest spacecraft ever launched was the Helios probe, which travelled approximately 70,000 m/s as it passed close to the Sun. The speed of light is 3x 10^8 m/s. Suppose the Helios probe passed by a stationary observer on Earth. The observer can see an accurate clock ticking on the side of the Helios Probe.How many seconds on Earth are equivalent to one second on the Helios probe?
In 2030, the Australian Space Agency launches a spaceship to our nearest neighbour Alpha Centauri, approximately 4 lightyears
away.
According to a clock on Earth how long will the rocket take to get there if it travels at v=0.999c=299482km/s (where 'c' is the
speed of light equal to 299782km/s)?
About 2 years.
O About 6 years.
O About 4 years.
Zero time.

- An alien spaceship traveling at 0.600c toward the Earth launches a landing craft. The landing craft travels in the same direction with a speed of 0.800c relative to the mother ship. As measured on the Earth, the spaceship is 0.200 ly from the Earth when the landing craft is launched. (a) What speed do the Earth-based observers measure for the approaching landing craft? (b) What is the distance to the Earth at the moment of the landing crafts launch as measured by the aliens? (c) What travel time is required for the landing craft to reach the Earth as measured by the aliens on the mother ship? (d) If the landing craft has a mass of 4.00 105 kg, what is its kinetic energy as measured in the Earth reference frame?arrow_forward(a) All but the closest galaxies are receding from our own Milky Way Galaxy. If a galaxy 12.0x109ly away is receding from us at 0.900c, at what velocity relative to us must we send an exploratory probe to approach the other galaxy at 0.990c as measured from that galaxy? (b) How long will it take the probe to reach the other galaxy as measured from Earth? You may assume that the velocity of the other galaxy remains constant. (c) How long will it then take for a radio signal to be beamed back?

During a space battle, a missile is shot from spaceship one toward spaceship two. The missile leaves the spaceship one at 0.960c (in spaceship one's reference frame) and approaches spaceship two at 0.752c (in spaceship two's reference frame). What is the relative velocity of the two spaceships in units of c? Hint: keep in mind that the two spaceships are approaching each other.
