Suppose that you exert 500 N horizontally on a 40-kg crate on a factory floor. The friction between the floor and the crate is 200 N. What is the acceleration of the crate?

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?
