Find the change in speed of a rock

Reference no: EM13699794

Compute all parts of following problem given below:

Problem: An attacker at the base of a castle wall 3.60 m high throws a rock straight up with speed 8.00 m/s from a height of 1.50 m above the ground.

Part A: Will the rock reach the top of the wall?

Yes/No

Part B: If so, what is its speed at the top? If not, what initial speed must it have to reach the top?

Part C: Find the change in speed of a rock thrown straight down from the top of the wall at an initial speed of 8.00 m/s and moving between the same two points.

Please do a step by step solution since I'm kind of lost with this problem.
