An attacker at the base of a castle wall 3.70 m high throws a rock straight up with a speed 8.30 m/s from a height of 1.68 m above the ground.

a) Will the rock reach the top of the wall?

b) What is the speed at the top? If not what initial speech must it have to reach the top?

c) Find the change in speed of a rock thrown straight down from the top of the wall at an initial speed of 8.30 m/s and moving between the same two points?
