The coefficient of kinetic friction between the block and the surface is μ = 0.4. If the block is initially moving up the plane at vo= 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 = 3 s.
