A block of mass m is being pulled up the rough incline by an agent delivering constant power P. The coefficient of friction between the block and the incline is μ. The maximum speed of the block during the course of ascent is
- \(v=\frac{P}{m g \sin \theta+\mu m g \cos \theta}\)
- \(v=\frac{P}{m g \sin \theta-\mu m g \cos \theta}\)
- \(v=\frac{2 P}{m g \sin \theta-\mu m g \cos \theta}\)
- \(v=\frac{3 P}{m g \sin \theta-\mu m g \cos \theta}\)
Answer
(A) v= P m g + m g
