Question: The 50-kg block is hoisted up the incline using the cable and motor arrangement shown. The coefficient of kinetic friction between the block and the

The 50-kg block is hoisted up the incline using the cable and motor arrangement shown. The coefficient of kinetic friction between the block and the surface is μ_k = 0.4. If the block is initially moving up the plane at v₀ = 2 m/s, and at this instant (t = 0) the motor develops a tension in the cord of T = (300 + 120√t) N, where t is in seconds, determine the velocity of the block when t = 2 s. v0 = 2 m/s 30

v0 = 2 m/s 30
