Question

A 950 kg car has a velocity of 13 m/s. What is the kinetic energy of the car?

Answer 1

Step-by-step explanation:

Kinetic energy = 1/2 × m × v^2

mass m = 950kg

Velocity v = 13m/s

Kinetic energy = 1/2 × 950 × 13^2

Kinetic energy = 475 × 169

Kinetic energy = 80275J

Answer 2

Answer: 80,275 J

Explanation: Kinetic energy is expressed as KE= 1/2 mv²

so substitute the given values of mass and velocity. KE = 1/2 ( 950kg)(13m/s)² = 80,275 J.
