The figure shows a cord attached to a cart that can slide along a frictionless horizontal rail aligned along an x axis. The left end of the cord is pulled over a pulley, of negligible mass and friction and at cord height h = 1.6 m, so the cart slides from x1 = 5.0 m to x2 = 1.0 m. During the move, the tension in the cord is a constant 27.0 N. What is the change in the kinetic energy of the cart during the move? Number Units

The figure shows a cord attached to a cart with mass = 1.2 kg that can slide along a horizontal rail aligned along an x axis with μk = 0.10. The left end of the cord is pulled over a pulley, of negligible mass and friction and at cord height h = 1.4 m, so the cart slides from x1 = 4.0 m to x2 = 1.0 m. During the move, the tension in the cord is a constant 27 N. What is the change in the kinetic energy of the cart during the move?

The figure shows a thin rod, of length L = 2.30 m and negligible mass, that can pivot about one end to rotate in a vertical circle. A heavy ball of mass m = 15.0 kg is attached to the other end. The rod is pulled aside to angle θ0 = 14.0∘ and released with initial velocity v→0 = 0. As the ball descends to its lowest point, (a) how much work does the gravitational force do on it and (b) what is the change in the gravitational potential energy of the ball-Earth system? (c) If the gravitational potential energy is taken to be zero at the lowest point, what is its value just as the ball is released? (a) Number Units (b) Number Units c) Number Units

The figure shows a thin rod, of length L = 1.50 m and negligible mass, that can pivot about one end to rotate in a vertical circle. A heavy ball of mass m−8.40 kg is attached to the other end. The rod is pulled aside to angle θ0 = 10∘ and released with initial velocity v0→ = 0. (a) What is the speed of the ball at the lowest point? (b) Does the speed increase, decrease, or remain the same if the mass is increased? (a) Number Units (b)
