A drop hammer is used to drive a hollow steel post into the ground. The hammer is placed inside the post by a crane. The crane lifts the hammer and then drops it so that it falls onto the baseplate of the post.

The hammer has a mass of 1800 kg. Its velocity is 5 m/s just before it hi is the post.

a. Calculate the kinetic energy of the hammer just before it hits the post.

b. How much potential energy has the hammer lost as it falls) Assume that it falls freely.

c. Calculate the distance the hammer has fallen. (Assume g = 10 N/kg)
