The total mass of thewagon, rider, and rock is 91.9 kg. The mass of the rock is 0.279 kg. Initially the wagon is rolling forward at a speed of 0.547 m/s. Thenthe person throws the rock with a speed of 16.3 m/s. Both speeds are relative to the ground. Find the speed of the wagon after the rockis thrown (a) directly forward in one case and (b) directly backward in another.(a) vi0.402(b) v = i0.505m/s.m/s

Two bodies of mass 4 kg and 6 kg are tied to the ends of massless string. The string passes over a pulley which is frictionless (see figure). The acceleration of the system in terms of acceleration due to gravity (g) is: 4 kg 6 kg
Lizzy is training on the trapeze when a slight accident occurs. As a result, she is now hanging from the middle of a 60 m safety rope connected to the ceiling on one end and held by a strongwoman from the circus on the other end. She has a mass of 50 kg and the part of the rope connected to the ceiling makes an angle of 55° with the vertical. The part of the rope that connects Lizzy to her fellow circus artist makes an angle of 20° above the horizontal (the strongwoman is above Lizzy). As long as Lizzy remains stationary, what is the tension in both parts of the rope?

Two masses with mass mA = 3.220 kg and mB = 22.81 kg, respectively, hang with a massless line over an inhomogeneous pulley with mass mC = 41.81 kg. The mass center of the pulley is located in the middle of the pulley. The pulley is attached with a frictionless bearing in the middle. g = 9,806 m / s². If mass A accelerates upwards by 5.75 m/s², what force then acts on the suspension of the inhomogeneous pulley?
