Question: You toss a tennis ball straight upward. At the moment it leaves your hand it is at a height of 1.3 m above the ground, and it is moving at a speed of 7.4 m/s.
Part A: How much time does it take for the tennis ball to reach its maximum height?
Part B: What is the maximum height above the ground that the tennis ball reaches?
Part C: When the tennis ball is at a height of 2.6 m above the ground, what is its speed?
I need help to determine the maximum height above the ground that the tennis ball reaches.
