The international space station is orbiting at an altitud of 370km above earth's surface. The mass of the earth is 6x10^24kg and the radius of the earth is 6378km.
a.) Assuming a circular orbit, what is the period of the space station?
b.) Assuming a circualr orbit, whit is the orbital speed of the space station?
A 1200g model rocket is resting horizontally at the top edge of a 40-m-high wall when it is accidentally bumped, How far from the base of the wall does the rocket land
A small circular hole 7.00 in diameter is cut in the side of a large water tank, 25.0 below the water level in the tank. The top of the tank is open to the air.
A certain car battery with a 14.0 V emf has an initial charge of 195 A•h. Assuming that the potential across the terminals stays constant until the battery is completely discharged, for how long in hours can it deliver energy at the rate of 184 W.

The first controlled, sustained flight in a heavier-than-air craft was made by Orville Wright on December 17, 1903. The plane took off at the end of a rail that was 60 feet long, and landed 12 seconds later, 180 feet away from the beginning of the..
Two nonconservative forces are present: friction does -2.00 104 J of work on the car, and a chain mechanism does +3.00 104 J of work to help the car up a long climb. Illustrate what is the change in the car's kinetic energy, ΔKE = KEf - KE0, fro..
