Question

Three forces act on a cargo canister that was initially stationary but that now moves across a frictionless floor. The force magnitudes are F_1 = 2.80 N. along the -x - axis: F_2 = 3.80 N, at theta_2 = 52.0; and F_3 = 100 N, at theta_3 = -122.0; What is the net work done on the canister by the three forces during the first 2.00 m of displacement? 16 J 4 J -16 J 3 J A child whose weight is 282 N sides down a 7.30 m playground slide that makes an angle of 34.0 degree with the horizontal. If she starts at the top with a speed of 0.320 m/s, and her speed at the bottom is 8.51 m/s, how much energy is transferred to thermal energy? 9045.46 J 110.68 J 1084.52 J 0 J
