An Atwood’s machine consists of blocks of masses m1=10.0 kg and m2 = 20.0 kg attached by a cord running over a pulley as in the figure below: The pulley is a solid cylinder with mass M=8.00 kg and radius r=0.200 m. The block of mass m2 is allowed to drop, and the cord turns the pulley without slipping. a) Why must the tension T2 be greater than the tension T1? b) What is the acceleration of the system, assuming the pulley axis is frictionless? 6 c) Find the tensions T1 and T2.

Aperson gives a shopping cart an initial push along a horizontal floor to get it moving, and then lets go. the cart travels forward along the floor, gradually slowing as it moves. consider the horizontal force(s) on the cart while it is moving forward and slowing. which of the following statements is correct? (a) both a forward and a backward force are acting on the cart, but the forward force is larger. (b) only a forward force is acting which diminishes with time. (c) both a forward and a backward force are acting on the cart, but the backward force is larger. (d) only a backward force is acting, no forward force.
