The coefficient of kinetic friction between the mass and the incline is \mu. If the mass continues to slide down the incline at a constant speed, how much energy is dissipated by friction by the time the mass reaches the bottom of the incline?
- \dfrac{mgh}{\mu}
- mgh
- \dfrac{\mu mgh}{\sin\theta}
- mgh\sin\theta
- 0
