We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?

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?

Often called simply "velocity," this is the velocity of an object at a particular moment in time.
