The 7-kg block A is released in the position shown with a velocity of 1.5 m/s up
Question:
The 7-kg block A is released in the position shown with a velocity of 1.5 m/s up the incline. Knowing that the velocity of the block is 3 m/s after it has moved 0.6 m up the incline, determine the work done by the friction force exerted on the block. Neglect the masses of the pulleys.
