Deimos, one of Mars's moons, has a mass of about 2.0 x 10¹5 kg and a diameter of about 12 km. An astronaut standing on the surface of Deimos wants to see if she can throw a baseball all the way around the moon. a. At what speed (in miles/hour) would she have to throw the ball so that it would move in a circular orbit just above the surface of the moon? (Assume Deimos is spherical.) b. How long would it take (in hours) before the ball returned to her if she threw it at the speed you found in part (a)? c. What is the free-fall acceleration g for Deimos, in m/s²?

A satellite of mass 200 kg is launched from a site on Earth’s equator into an orbit 200 km above the surface of Earth. a. What is the satellite’s speed before it’s launched (in m/s)? (Hopefully, it’s moving along with the surface of the Earth as the Earth rotates.) b. What is the satellite’s speed in its orbit (in m/s)? (Remember there is only onespeed a satellite can have in order to maintain a stable circular orbit with agiven radius.) c. Assuming a circular orbit, what is the orbital period of this satellite? (In other words, how long (in hours) does it take for the satellite to complete one orbit?) d. What is the minimum energy (work) necessary to place the satellite in orbit,assuming no air friction? (Remember, work is the amount of energy added tothe system, and the total energy of the system is a combination of kinetic andgravitational potential energies.)

You are on a boat in the middle of the Pacific Ocean at the equator traveling in a hydrofoil going at a constant speed of 300 ?/?. The water is perfectly still. What is your acceleration: a) If you're heading due North? b) If you're heading due East? c) If you're heading straight up (something probably went wrong at this point). Assume the following: The earth has a radius of 6371 km. The earth makes one full revolution every 24 hours. The gravitational constant at sea level is 9.81 m/s2. East and North are relative to the Earth's axial north, not magnetic north.
