Answer to Question #131999 in Physics for Sara

Question

A boy throws a ball vertically upwards, because of air resistance/air drag, the ball:

a) takes the same time going up and coming down
b) undergoes a constant drag force
c) takes longer going up compared to coming down
d) takes longer moving down compared to going up

Answer 1

For the ball it takes the same time going up and coming down. The drag force depends on velocity and shape of the ball. Velocity depends on acceleration due to gravity. Therefore, the drag force will act the same way in both cases.
