A 2.6 kg block is attached to a horizontal rope that exerts a variable force Fx = (20 - 5x) N, where x is in m. The coefficient of kinetic friction between the block and the floor is 0.25. Initially the block is at rest at x = 0 m. What is the block's speed when it has been pulled to x = 0.80 m? V= μÀ 1 Value m S ?
