Compute each part of following problem given below:
Problem: A tennis ball on Mars, where the acceleration due to gravity is 0.379 of a g and air resistance is negligible, is hit directly upward and returns to the same level 6.60s later.
Part A: How high above its original point did the ball go?
Part B: How fast was it moving just after being hit?
I don't know how to get that answer for the above problem. Please help! Thanks.
