Question

What is the kinetic energy of the silver sphere at the moment it hits the ground? (Assume that energy is conserved during the fall and that 100% of the sphere’s initial potential energy is converted to kinetic energy by the time impact occurs.)

Answer 1

Answer:

Kinetic Energy = 0

Explanation:

No matter if energy is totally conserved during the fall or when it hits the ground, the kinetic energy of the silver sphere will be zero because the velocity component in $K.E = 1/2mv^{2}$ becomes zero, the over all energy becomes zero.
