[-/4 Points] DETAILS SERPSE10 8.1.P.001. 0/6 Submissions Used MY NOTES ASK YOUR TEACHER Consider the conservation of energy equation below AK + AU + AEint = W+ Q+ TMW+TMT+ TET+ TER A ball of mass m falls from a height h to the floor. (a) Identify the appropriate version of the equation above for the system of the ball and the Earth. O AEint = Q +TET + TER O AK + AU = 0 O AU = W O AK = W 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.) V = (b) Identify the appropriate version of the equation above for the system of the ball. OAK + AU = 0 O AEint = Q +TET + TER O AU = W O AK = W Use this equation to calculate the speed of the ball just before it strikes the Earth.
