Question

A car is moving at 12 m/s and has a mass of 600 kg. What is the kinetic energy of the car? (Formula: KE = 1/2 mv^2)

Answer 1

The kinetic energy of the car is 43,200 Joules.

Step-by-step explanation:

Answer 2

KE = (1/2)mv^2

KE = (1/2)(600 kg)(12 m/s)^2

KE = (1/2)(600 kg)(144 m^2/s^2)

KE = 43,200 kg*m^2/s^2 = 43,200 Joules

The kinetic energy of the car is 43,200 Joules.
