Question 6 a) Apply the work equation to determine the amount of work done by the applied force in each of the three situations described below. Diagram A F-100 N 15 kg A 100 N force is applied to move a 15 kg object a horizontal distance of 5 metres at constant speed. Diagram B F = 100 N 15 kg 30° A 100 N force is applied at an angle of 30° to the horizontal to move a 15 kg object at a constant speed for a horizontal distance of 5 m. Form - 20 N Diagram C b) For each situation below, indicate which force(s) are doing work upon the object. Then calculate the work done by these forces. Fapp-10 N 15 kg A 10N force is applied to push a block across a friction free surface for a displacement of 5.0m to the right. Fgrav = 20 N An upward force is applied to lift a 15 kg object to a height of 5 metres at constant speed. An approximately 2kg object is sliding at constant speed across a friction free surface for a displacement of 5m to the right. Fnorm = 20 N/nsurface for a displacement of 5m to the right. Fnorm = 20 N Fgrav = 20 N c) A cart is loaded with a brick and pulled at constant speed along an inclined plane to the height of a chair top. If the mass of the loaded cart is 3.0kg and the height of the chair top is 0.45m, then what is the potential energy of the loaded cart at the height of the chair top? If a force of 14.7N is used to drag the loaded cart along the incline for a distance of 0.90m, then how much work is done on the loaded cart? d) Determine the kinetic energy of a 625kg roller coaster car that is moving with a speed of 18.3m/s. 5
