Kinetic energy is the energy that is possessed by an object that is moving. It is calculated by one-half the product of the mass and the square of the velocity of the object. We calculate as follows:

KE = mv^2 / 2
KE = 908 kg (89 km/hr ( 1000 m / 1 km) ( 1 hr / 3600 s ))^2 / 2
KE = 277479.48 J or 204658.05 ft-lbf
