Question

How much kinetic energy does an 80 kg man have while running at 3 m/s?

Answer 1

Hello!

$\large\boxed{KE = 360 J}$

Use the equation KE = 1/2mv² to solve for the kinetic energy of the man.

We are given the mass and velocity, so plug these values into the equation:

KE = 1/2(80)(3²)

KE = 1/2(720)

KE = 360 J
