Two boulders are rolling down a hill towards Susie. If Susie wanted to try to stop the boulder with less kinetic energy, which of these should she choose? Why?
Boulder A with a mass of 45kg and a speed of 25km/hr
Boulder B with a mass of 20kg and a speed of 25km/hr.
What is boulder B? It has less mass so it has less Kinetic energy.
