Kinetic energy refers to the energy of an object in motion. The amount of energy an object has (K) is related to the mass of the object (m, measured in kg), and its velocity (v, measured in m/s). The formula used to calculate kinetic energy is
K = _12 m v 2.
1. Solve for m if K = 486 and v = 9 m/s.
K = _12 m v 2.
