A 3.69 kg ball is dropped from the roof of a building 162.6 m high. While the ball is falling to Earth, a horizontal wind exerts a constant force of 13.6 N on the ball.
How far from the building does the ball hit the ground?
Answer in units of m.
What is its speed when it hits the ground?
Answer in units of m/s.
