Details: A cart is attached to a hanging mass by a string that passes over a pulley. When the cart moves on an incline at constant speed, it is in equilibrium; ie, the net force on it is zero.
Question: Derive an equation for the work done by friction when the cart is moving up the track at constant speed.

1. An unknown mass (mı) on a rough horizontal surface is attached by a wire that passes over a massless, frictionless pulley to a 2.50kg mass (m2) as shown below. The bottom of the hanging mass is 1.50m above the floor. The system is released from rest at t-0s and the 2.50kg mass strikes the floor 0.82s later. The system is now returned to its initial position and a 1.20kg mass is placed on top of the block of mass...

14. Two masses are connected by a string which passes over a pulley with negligible mass and friction. One mass hangs vertically and one mass slides on a frictionless 30.0 degree incline. The vertically hanging mass is 6.00 kg and the mass on the incline is 4.00 kg. The magnitude of the acceleration of the 4.00 kg mass is 15. Two masses are connected by a string which passes over a pulley with negligible mass and friction. One mass hangs...

Cart on an Incline plane. Start up the Dynamics Track apparatus. Set the µKS? # stepper to zero (µk = 0.12 and µs = 0.18 by default). Please notice that the dynamic track has a feature to be tilted by dragging when the mouse cursor is in the colored part of either end of the track. The message box informs that the track can be tilted up or down. With the brake off, turn on the friction pad and put...

Cart A (mass 2.0 kg) and Cart B (mass 3.0 kg) are separated by a compressed spring and attached to each other by a string. Initially they are sitting at rest on a frictionless surface. When the string is burned, Cart A moves to the left at 1.5 m/s. Cart B moves to the right and encounters a rough surface. Cart B comes to a stop after traveling a distance of 0.35 m on the rough surface. What is the...
