A ball is thrown directly upwards with a velocity of 29.0 m/s. What is the maximum height the ball will go ? (Assume g= 9.80m/s2 and no air resistance) h = m. The ball will remain in flight for s. (Use 3 sig figs)

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?
