4) A block of 1 kg falls from a vertical cliff of height 100m.
a) Calculate the velocity of the block right before it hits the ground?
b) Calculate the work done on the block by gravity?
c) Is this work negative, positive or zero, explain why?
d) Assume the block didn't bounce after it hits the ground, calculate the velocity
of Earth, caused by impact, in the direction of the moving block, right after the
collision with the block. Mass of Earth = 6 x 1024kg.
