You arrange to meet a friend at 5:00 p.m. on Valentine’s Day on the observation deck of the Empire State Building in New York City. You arrive right on time, but your friend is not there. She arrives 5 minutes late and says the reason is that time runs faster at the top of a tall building, so she is on time but you were early. Is your friend right? Does time run slower or faster at the top of a building, as compared with its base? Is this a reasonable excuse for your friend arriving 5 minutes late?
The New Horizons probe that passed by Pluto during July 2015 is one of the fastest spacecraft ever assembled. It was moving at about 14 km/s when it went by Pluto. If it maintained this speed, how long would it take New Horizons to reach the nearest star, Proxima Centauri, which is about 4.3 light-years away? (Note: It isn’t headed in that direction, but you can pretend that it is.)
A spaceship moves away from Earth at a speed v and fires a shuttle craft in the forward direction at a speed v relative to the ship. The pilot of the shuttle craft launches a probe at speed v relative to the shuttle craft. Determine (a) the speed of the shuttle craft relative to Earth, and (b) the speed of the probe relative to Earth.
Choose the option from each pair that makes the following statement correct. Because for an object in relative motion is always [(a) greater, (b) less] than 1, a proper time interval tp is always [(c) longer; (d) shorter] than the time interval t and a proper length Lp is always [(e) longer; (f) shorter] than the length L.

If you use an Earth based telescope to project a laser beam onto the moon, you can move the spot across the moon's surface at a velocity greater than the speed of light Does this violate modern relativity? (Note that light is being sent from the Earth to the moon, not across the surface of the moon.)
The Sun orbits the Milky Way galaxy once each 2.60108 years, with a roughly circular orbit averaging a radius of 3.00104 light-years. (A light-year is the distance traveled by light in 1 year.) Calculate the centripetal accleration of the Sun in its galactic orbit. Does yur result support the contention that a nearly inertial frame of reference can be located at the Sun? (b) Calculate the average speed of the Sun in its galactic orbit. Does the answer surprise you?
An astronaut is traveling in a spacecraft in outer space in a straight line at a constant speed of 0.500c. Which of the following effects would she experience? (a) She would feel heavier. (b) She would find it harder to breathe. (c) Her heart rate would change. (d) Some of the dimensions of her spacecraft would be shorter. (e) None of those answers is correct.
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.
a clock on a space rocket ticks off at a time interval of1hour. what is the time elapse on earth if the rocket is travelling at aspeed ofi). 1650km/hr ? and ii). 0.9c ? [c =3.0 x10 8m/s]
Wonder Woman and Superman fly to an altitude of 1630 km,1630 km, carrying between them a chest full of jewels that they intend to put into orbit around Earth. They want to make this tempting treasure inaccessible to their evil enemies who are trying to gain possession of it, yet keep it available for themselves for future use when they retire and settle down. But perhaps the time to retire is now! They accidentally drop the chest, which leaves their weary hands at rest, and discover that they are no longer capable of catching it as it falls into the Pacific Ocean. At what speed ?fvf does the chest impact the surface of the water? Ignore air resistance (in reality, it would make large difference). The radius and mass of Earth are 6370 km6370 km and 5.98×1024 kg,5.98×1024 kg, respectively.
The spaceship Lilac, based on the Purple Planet, is 711 m long when measured at rest. When the Lilac passes Earth, observers there measure its length to be 655 m. At what speed ? is the Lilac moving with respect to Earth? Express your answer as a multiple of the speed of light ?.
