A Martian leaves Mars in a spaceship that is heading to Venus. On the way, the spaceship passes earth with a speed v = 0.88c relative to it. Assume that the three planets do not move relative to each other during the trip. The distance between Mars and Venus is 1.20 × 1011 m, as measured by a person on earth. (a) What does the Martian measure for the distance between Mars and Venus? L = (b) What is the...
As the astronaut chose for the one-way mission to Mars, one of your tasks is to measure g. You have a long very thin wire labelled “1 g/m”, and a 125 g weight. You have an accurate chronometer, but forgot a meter stick, so you fold the wire in two to find its centre. You attach one end of the wire to the wall, stretch it horizontally to pass over a pulley at its midpoint, then suspend the weight on...
The Mars rover was deployed on the surface of Mars in July 1997. At one point during its subsequent mission, radio signals took about 9 min to travel from Earth to the rover. How far was Mars from the from Earth at that time? ___ m
Astronaut Flo wishes to travel to a star 20 light years away and return. Her husband Malcolm, who was the same age as Flo when she departs, stays home (baking cookies). If Flo travels at a constand speed of 80% of the speed of light (except for a short time to turn around), how much younger than Malcolm will Flo be when she returns?Hint--How long does Malcolm sit around baking cookies? How far is the distance to Flo?
2. Mars is currently 35.8 million miles away from Earth. How long would it take to send a radio signal to the Curiosity rover on Mars and receive an answer from the rover, assuming that the rover answers instantly? In other words, what is the round trip travel time for an electromagnetic wave to Mars right now? Recall that c = 3.00 x 108 m/s. Also, 1 mile = 1.61 km. Answer in minutes.

3. At its closest approach to Earth, Mars is 57.50 million kilometers away. How long in minutes) would a radio signal sent from a future manned mission to Mars take to travel to Earth? (distance = speed x time)
