Solve the all parts of given question:
Question: A small rubber ball is launched by compressed-air cannon from ground level with an initial speed of 11.8 m/s directly upward. Choose upward as the positive direction in your analysis.
Part A: What is the maximum height above the ground that the ball reaches?
Part B: How long does it take to reach the maximum height?
Part C: How long does it take to reach the ground after it reaches its highest point?
Part D: What is its velocity just before it hits the ground? (Indicate the direction with the sign of your answer.)
I need help to determine the maximum height above the ground that the ball reaches.
