A student drops a small metal sphere from a vertical height of 2.5 m2.5\text{ m}2.5 m above the ground. The sphere falls to the ground and does not bounce after hitting the ground.
Describe the transfers of energy of the sphere between stores from when the sphere is released to after it has hit the ground.
Calculate the maximum speed of the sphere. Ignore air resistance. (Take g=9.8 m/s2g = 9.8\text{ m/s}^2g=9.8 m/s2)
