On Mars, a ball is rolling from a ground to a hill, and we know the height of the hill, Z, is 10 m, and the initial velocity ofthe ball on the ground and the final velocity on the hill are known: V1 = 20 m/s and V2 = 10 m/s, respectively. The mass ofthe ball, m, is 4 kg. The gravitational acceleration on Mars, gMars, is 3.7 m/s2. Please calculate 1) the change in kineticenergy, ΔKE, in J and 2) the change in potential energy, ΔPE, in J, of the ball for the rolling process.
