What is the period of a wave generated by an
earthquake, if it has a wavelength of 500 meters and a
speed of 5,000 meters per second?

How much work is done lifting a 9.10 kg box straight up onto a shelf that is 1.80 m high?

An artificial satellite circles the earth in a circular orbit at a location where the acceleration due to gravity is 6.03 m/s^2. determine the orbital period of the satellite.

Aboxcar traveling at 12 m/s approaches a string of 5 identical boxcars sitting stationary on the track. the moving boxcar collides and links with the stationary cars and they all move off together along the track. what is the final speed of the cars immediately after the collision? (you may take the mass of each boxcar to be 18,537 kg.)
