MECHANICAL ENERGY

A $0\mathrm{.}028-kg$ ball is launched vertically with an initial speed of $4\mathrm{.}2\frac{m}{s}.$ If air resistance is negligible, to what maximum height will the ball rise? $($Use conservation of mechanical energy in answering this question.$).$

An object that has been released from rest above Earth's surface gains kinetic energy as it falls. Where does the kinetic energy of the object come from?
