A block weighing 50-kg is being pulled up the incline as shown below. The coefficient of kinetic friction between the block and the surface of the incline is 0.4. If the block is initially moving up the plane at 2m/s and at this instant (t = 0) the motor develops a tension in the cord of T = (300 + 120vt) Newtons, where t is time in seconds. Determine the velocity of the block at t = 25.
