Please answer what are the possible errors and part C
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 careJl not to let your angle change inadvertently during this actrvrty. Also, measure the mass of your cart using one of the scales. . y o n measured angle: 02%? . 39 measured mass of cart: 00 7. 752 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 Specically, draw separate free body diagrams in the space below for the cart and the hanging basket. Apply Newton's laws to calculate the specic 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. ,__. n . ,- p A / _/ '17 P predicted mass of basket: ii (/72. Qj 2. Make a basket that can hang down and hold weights. Connect string to your cart, pass it over the pulley, and tie it to your basket. Is it important that the string over the track is parallel to the track? Add mass to the basket to achieve balance between the cart and the hanging mass. You can use pennies to nely adjust the mass. Finally, measure the mass of the basket that achieves balance. measured mass of basket: {50 Q 0 . 6 /o percentage error relative to predicted mass of basket: possible sources for the error: C. equilibrium with static friction Balancing the cart on the inclined plane in the presence of friction 1. Reset the balance between the cart and hanging mass from part B. Now turn your cart upside down (with the wheels facing up away from the track) so that the cart has friction against the track. The cart should remain in balance. Add small amounts of mass to the basket until the cart just starts to move up the inclined plane. Measure the mass of the hanging basket that just barely causes the cart to move, measured mass of basket: 92730 g 2. Calculate the coefcient of static friction between the cart and the track. Specifically, draw separate free body diagrams in the space below for the cart and the hanging basket. Apply ' Newton's laws to calculate the coefficient of friction. Assume that the static friction force has 1ts maxrmum value (us N) at this moment that the cartjust starts moving. Use your measured angle and the measured masses of your cart and hanging basket. calculated coefcient of static friction, us
