3. A cargo of 2 Kg on a frictionless ramp is connected (by a cord that runs over a pulley) to a spring of k= 120 N/m. The cargo is released from rest when the spring is unstretched. Assume that the pulley is massless and frictionless. 3A. (5 points) Provide the free body diagram of the cargo. 3B. (14 points) When the cargo when it has moved 10 cm down the inclined: Calculate the work done on the cargo by the gravitational force. Calculate the work done on the cargo by the spring force. Calculate the speed of the cargo 3C. (14 points) Calculate how far down the inclined from its point of release does the cargo slide before momentarily stopping. 2 kg 40⁰ k =120 N/m
