Kinetic energy varies jointly with the mass (m) of an object and the square of it's velocity (u). A ball with a mass of 6 kg rolls with a velocity of 10 m/s and creates 300 joules of kinetic
energy. How much kinetic energy would a ball with a mass of 3 kg and a velocity of 5 m/s create? (First find the constant of variation)
A. 75 joules
B. 37.5 joules
C. 202.5 joules
D. 7.5 joules
