Question

Marissa drags a 23 kg duffel bag 18 m across the gym floor. if the coefficient of kinetic friction between the floor and bag is 0.15, how much thermal energy does marissa create?

Answer 1

The answer for this question is computed by:
The work done by friction would be equal to the thermal energy.
23 * 9.8 = 225.4 N
225.4 * .15 = 33.81 N is the Force of friction
33.81 *18 = 608.58 J of work done by friction is now also 608.58 J of thermal energy.
