One way to measure the amount of energy that a moving object (such as a car) possesses is by finding its Kinetic Energy. The Kinetic Energy (Ek, measured in Joules) of an object depends on the objeet's mass (m, measured in kg) and velocity (o, measured in meters per second), and can be wrtten as What is the Kinetic Energy of an object with a mass of 1,100 kilograms that is traveling at 30 meters per second? ER- 2E Joules
