A 3.00 kg ball is dropped from the roof of a building 176.4 m high. While the ball is falling to Earth, a horizontal wind exerts a constant force of 12.0 N on the ball. How long does it take to hit the ground?
How far from the building does the ball hit the ground?
What is its speed when it hits the ground?

a.)How far from the building does the ball hit the ground?

72 m

b.)How long does it take to hit the ground?

6 s

c.)What is its speed when it hits the ground?

63.48 m/s

Explanation:

When an object is in free fall with no air resistance present or wind acting on it it only is under the influence of gravity. Gravity acts straight down and accelerates the object all the way to the ground. If there is air resistance or a wind force on the object it will have an acceleration that isn't 9.8 m/s^2

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
