We watched an experiment to investigate the relationship between energy and speed. A ball was released from different points on a ramp. The data from the experiment is recorded in the image. Using the data, what can we conclude about energy and speed?

• The more energy we gave the ball, the faster the ball traveled.

• The less energy we gave the ball, the faster the ball traveled.

• It didn't matter how much energy we gave the ball, it always traveled at the same speed.

• The ball had the most speed when we released it from 21cm on the ramp.
