18. A pulley device is used to hurl projectiles from a ramp (LA = 0.26) as illustrated in the diagram. The 5.0-kg mass is accelerated from rest at the bottom of the 4.0 m long ramp by a falling 20.0-kg mass suspended over a frictionless pulley. Just as the 5.0-kg mass reaches the top of the ramp, it detaches from the rope (neglect the mass of the rope) and becomes projected from the ramp. (a) Determine the acceleration of the 5.0-kg mass along the ramp. [2 marks] (b) Determine the tension in the rope during the acceleration of the 5.0-kg mass along the ramp. [1 mark] (c) Determine the speed of the 5.0-kg mass at the top of the ramp. [2 marks] Bonus (1 A mark): Determine the horizontal range of the 5.0-kg mass from the base of the ramp. 4.0 m Hx=0.26 5.0kg 300 20.0 kg 6.0 m
