# Kinetic Energy & Stopping Force of a Car

A car of mass 1500 kg is moving with a speed of 50 km/h (13.89 m/s). Determine the kinetic energy T of the car.

(see options a through d in attached file)

Now determine the force required to stop the car at a distance of 50 m, if the kinetic energy T is 1.447 x 10E5 N-m. 10E5 means 10 to the 5th power.

a. 1447 N

b. 2894 N

c. 3000 N

d. 5000 N
