Consider the conservation of energy equation below. K + U + Eint = W + Q + TMW + TMT + TET + TER A ball of mass m falls from a height h to the floor. Identify the appropriate version of the equation above for the system of the ball. Use this equation to calculate the speed of the ball just before it strikes the Earth. (Use the following as necessary: m for mass, h for height, g for acceleration due to gravity.)
