A crumpled paper ball is falling from a tall building. It weighs 0.1 Newtons. After falling 20 meters the paper ball is no longer accelerating.
What must be the net force on the paper ball?
| 0.1 Newtons down |
| zero |
| Some value a little bit less than 0.1 N up |
| 0.1 Newtons up |

A crumpled paper ball is falling from a tall building
After falling 20 meters the paper ball is no longer accelerating
using Newton's seccond law
Fnet = m * a
as the acceleration is zero
Fnet = 0
the net force on the ball is (zero)

The Empire State Building in New York City is 381 meters tall. If a penny were dropped from rest at that height, how many seconds would it take to strike the street below? Air resistance would make a significant difference in the real world case, but ignore air resistance for now. As a 5 kg ball rolls down a ramp, the net force on it is 15 N. What is its acceleration? A long-distance runner has an average speed of...

A blue ball is thrown upward with an initial speed of 22.2 m/s, from a height of 0.8 meters above the ground. 2.7 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 9.2 m/s from a height of 27.8 meters above the ground. The force of grandly due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s^2. What is the speed of...
