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.
