Compute all parts of given question:
Question: A diver springs vertically upwards from a 4.5-m board with an initial speed of 4.2 m/s.
Part A: What is the maximum height that she reaches above the water?
Part B: What is her acceleration when she is at this maximum height?
Rework your solution from the starting and check each step carefully.
