Bowling ball is dropped from top of building

Reference no: EM13674683

A bowling ball is dropped from the top of a building that has a height of h = 135 m.

1) Assuming air resistance is negligible, what is the ball's speed, vf in m/s, when it strikes the ground?

2) If drag produces an opposing force of 10 N whilst the ball's falling, what is the ball's speed, vf in m/s, when it strikes the ground? Suppose the ball has a mass of 5 kg.

3) A different ball was dropped and the final speed was gauged to be vf = 6.5 m/s while the drag force was measured to be 50 Newton’s. What is the mass of this ball in kg?
