Finding the Force on a Ball from a Dent (10:24)
We use the Work Energy Theorem to solve the following … A 67 N ball is dropped from a height of 79.8 cm above a bag of sand. If the ball makes a 9.0 mm deep dent in the sand, what is the average force the sand applies on the ball during the collision? This is an AP Physics 1 and AP Physics C: Mechanics topic.
