3 4 A bowling ball and a feather are dropped from the top of a high building. They are released at the same time. The bowling ball reaches the ground first. Which statement explains this? A The acceleration of free-fall is greater for the bowling ball as compared to the feather. B The bowling ball reaches a greater speed before the air resistance acting on it balances its weight. C The gravitational field causes the feather to accelerate slower than the bowling ball. D There is a smaller force of air resistance on the feather. 5 Which moving body has
