Solve the following question given below:
Question 1: You throw a ball vertically upward at 27.0 m/s, and then catch it at the same height you released it. Ignoring air resistance, how high did the ball rise?
Question 2: Ignoring air resistance, how long will it take for the ball to return to your hand? Enter the time for the total trip.
Question 3: What is the ball's speed just before it returns to your hand?
Having trouble with this physics questions, can you please explain with the answer.
