In which position does the ball have the least potential energy but the most kinetic energy

What is the final velocity of the initial velocity of 25 and -50?

Wavelength, frequency, and energy are related. what happens to a wave as it’s wavelength gets shorter?

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?
