change in kinetic enegery)
KE20. Figure shows a mechanism. Body 5 is assumed to be homogeneous circular cylinder, and mass of the pulley 4 is uniformly distributed over its rim. The coefficient of sliding friction between bodies and the plane is f 0.1 The coefficient of stiffness of a spring is c. A force F applied to the mechanism depends on the displacement s of the body 1. The mechanism starts motion...

А D z Problem 3. Work done by gravity and change in gravitational potential energy In problem the box was moving in a horizontal direction, and therefore no work was done by gravity. Here, we will analyze a situation where the force of gravity has some component that points along the direction of the displacement, and therefore there is non-zero work done by gravity on the system of interest Consider a box of mass 10 kg, initially at rest, which...

Problem 3 (20 points) In the following figure, a horizontal force F is applied to a large block of mass M with a massless pulley attached to it. While the block M is moving to the right, the other two blocks mi and m2 remain stationary problem relative to M. All surfaces are frictionless for this (a) Draw separate free body diagrams for M(including the massless pulley), mi, and m2 respectively. On the free body diagrams, please only draw and...
