Question 1 (6 marks) A tennis ball is thrown upward into the air. It then falls back to the starting position. 0 a) Draw a free body diagram of the tennis ball after it is thrown into the air and describe how the velocity of the tennis ball varies during its motion. [2] The same tennis ball is then projected into the air. A graph of height H against horizontal distance, D, is shown Height (m) Q S D (m) p T Points P, Q, R. S and T are at equal intervals in time. b) At which other point or points would the tennis ball have the same acceleration as at point R? [1] c) If the initial horizontal component of the velocity is 200 km h" and the horizontal range of the projectile is 50.0 Hi, what was the projectile's maximum height? [3]
