Set your track up at an angle with a pulley at the high end and with room for a mass to hang down from the pulley. Make measurements to accurately determine the angle of your track. Make your angle at least 20. Be careful not to let your angle change inadvertently during this activity. Also, measure the mass of your cart using one of the scales. sin -4_ 46 = 22. 340 124 cm 46 CM angle measured angle: 22. 34 0 measured mass of cart: 509. 79 B. frictionless equilibrium Balancing the cart on the inclined plane with a hanging mass 1. Predict the mass of the hanging basket that will balance the cart. Specifically, draw separate free body diagrams in the space below for the cart and the hanging basket. Apply Newton's laws to calculate the specific basket mass that should balance your cart. It might be useful to calculate the tension in the thread as an intermediate step. Assume that the friction between the cart and the track is negligible. Use your measured angle and the measured mass of your cart. Show all your calculations in detail. m - Intyn T-mn Sing. R, Norcotanic Ill Po 3. Predict the minimum mass of the hanging basket that will barely balance the cart, before it begins to slide down the inclined plane. Specifically, draw separate free body diagrams in the space below for the cart and the hanging basket. Apply Newton's laws to calculate the specific basket mass that should barely balance your cart. Use your measured angle, the measured mass of your cart, and the static coefficient of friction that you calculated in step 2 above. MS = 0.564 predicted mass of basket: 4. Reset your cart and hanging basket with the cart upside down. Remove mass from the basket until the cart just starts to move down the inclined plane. Measure the mass of the hanging basket that just barely allows the cart to slide down. measured mass of basket: 50q percentage error relative to predicted mass of basket: possible sources for the error
