Calculate the kinetic energy in joules of a 150 lb jogger (68.1 kg)traveling at 12.0 mile/hr (5.36 m/s).

Question

Quizplus · Accepted Answer

First, we need to convert the weight from pounds to kilograms:
150 lb = 68.1 kg
Next, we need to use the equation for kinetic energy:
Kinetic Energy = 1/2 * mass * velocity^2
Plugging in the numbers:
Kinetic Energy = 1/2 * 68.1 kg * (5.36 m/s)^2
Kinetic Energy = 978 J
Therefore, the answer is choice C.
