- Energy conservation with conservative forces: A very small 100-g object is attached to one end of a massless 10-cm rod that is pivoted without friction about the opposite end. The rod is held vertical, with the object at the top, and released, allowing the rod to swing. What is the speed of the object at the instant that the rod is horizontal? 1.8 m/s 1.4 m/s 0.71 m/s 2.8 m/s 4.0 m/s fbbIn the figure the pulley has negligible mass, and both it and the inclined plane are frictionless. Block A has a mass of 1.3 kg, block B has a mass of 2.2 kg, and angle 0 is 32°. If the blocks are released from rest with the connecting cord taut, what is their total kinetic energy when block B has fallen 28 cm? Number Units BA3

- A horizontal carousel is rotating around its axis with constant angular velocity w. On the carousel there is a straight track passing through its middle. A cart of mass m is traveling along the track with constant velocity v relative to the carousel. Note that there is friction between the cart and the carousel. FR XRCurrent Attempt in Progress A fully loaded, slow-moving freight elevator has a cab with a total mass of 1600 kg, which is required to travel upward 40 m in 1.6 min, starting and ending at rest. The elevator's counterweight has a mass of only 870 kg, so the elevator motor must help pull the cab upward. What average power is required of the force the motor exerts on the cab via the cable?
