A 3 kg bowling ball is thrown onto a mattress. If it takes 0.3 seconds to stop the ball using a force of 24 N, what was the initial velocity of the bowling ball when it first touched the mattress?

14000 kg car is moving at the speed of 2 miles per second how much kinetic energy does the car have

Where does energy go when an object hits the ground?

What causes the sky to be blue

Electromagnetic radiation with a frequency of 8.6 x 1014 hz incident on an unknown metal surface causes ejection of photoelectrons with kinetic energies of 1.3 x 10-19 j. what is the unknown metal?

An object is placed in a fluid and then released. Assume that the object either floats to the surface (settling so that the object is partly above and partly below the fluid surface) or sinks to the bottom.
