6. The tower of Pisa is 54.5 m tall. Assuming that Galileo dropped his object from rest from the top of the tower and that the effects of air resistance were negligible, how long would it take the object to fall, in seconds? What is the velocity of the object when it hits the ground? 7. A ball is thrown directly downward with an initial speed of 9.50 m/s from a height of 30.0 m. After what time interval does...

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.
