A jogger whose mass is 70 kg is moving at a speed of 3 m/s. What is the jogger’s kinetic energy?
The formula for kinetic energy is KE = 0.5 * mass * velocity^2.
Plugging in the values, we get:
KE = 0.5 * 70 kg * (3 m/s)^2
KE = 0.5 * 70 kg * 9 m^2/s^2
KE = 315 kg * m^2/s^2
The jogger's kinetic energy is 315 kg * m^2/s^2.
