Question: A tennis player hits a ball at ground level, giving it an initial velocity of 21.0m/s at 60.0 degree above the horizontal.
Part A: What are the horizontal vh and vertical vv components of the ball's initial velocity?
Part B: How high above the ground does the ball go?
Part C: How long does it take the ball to reach its maximum height?
Part D: What is the ball's velocity at its highest point?
Part E: What is the ball's acceleration at its highest point?
Part F: For how long a time is the ball in the air?
Part G: When this ball lands on the court, how far is it from the place where it was hit?
I need help to determine the ball's acceleration at its highest point.
