Question

A runner with a mass of 75 kg is running at a speed of 2 m/s. What’s the kinetic energy of the runner? Write the equation and show your math steps. Circle the mass and underline the velocity.

Answer 1

150 J

Step-by-step explanation:

Kinetic Energy = 1/2 m v ^2

KE = 1/2 ( 75)(2^2) = 150 kg m^2/s^2 = 150 J
