A child with a mass of 38.0 kg is swinging on a rope tire swing with a length L = 2.70 m (see picture below). The tire has a mass of 19.0 kg. When the swing is at its lowest point it has a speed of 4.00 m/s. What is the tension in the rope when the swing and child are at the lowest point? Give your answer rounded to the nearest Newton. Do NOT include units in your answer.

In a truck-loading station at a post office, a small 0.200 kg package is released from rest at point A on a track that is one-quarter of a circle with radius 1.60 m (Figure 1). The size of the package is much less than 1.60 m, so the package can be treated as a particle. It slides down the track and reaches point B with a speed of 5.40 m/s. From point B, it slides on a level surface a distance of 3.00 m to point C, where it comes to rest. Figure 1 of 1 m = 0.200 kg Part A What is the coefficient of kinetic friction on the horizontal surface? Submit Request Answer Part B How much work is done on the package by friction as it slides down the circular arc from A to B ? Express your answer in joules. Submit Request Answer

A 13.0 kg stone slides down a snow-covered hill (Figure 1), leaving point A at a speed of 12.0 m/s. There is no friction on the hill between points A and B, but there is friction on the level ground at the bottom of the hill, between B and the wall. After entering the rough horizontal region, the stone travels 100 m and then runs into a very long, light spring with force constant 2.10 N/m. The coefficients of kinetic and static friction between the stone and the horizontal ground are 0.20 and 0.80 , respectively. Figure 1 of 1 Part A What is the speed of the stone when it reaches point B? Express your answer in meters per second to three significant figures. v2 = m/s Submit Request Answer Part B How far will the stone compress the spring? Express your answer in meters to three significant figures. x = Submit Request Answer Part C Will the stone move again after it has been stopped by the spring? yes no
