a 60 kg diver dives from a platform 12 m above the surface of the water. when she hits the water, the friction with the water slows her to a stop in 3.08 meters. what is the magnitude and direction of the force the water friction on the diver?

What are two different ways you could find the value of a? explain these methods.

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?

The heliocentric and the geocentric models of the solar system included these central principles
