^ The pulley makes it so that the second mass exerts a force purely in the x direction, not affecting the normal force. I used left (or down, for the second mass), as the positive direction. The force exerted by mass m is equal to its mass times gravity, and delta-x equals 2.47 as provided in...

Help: Kinetic Energy and Friction -- A block pulled by another on a pulley In the system the following diagram shows, the block M (mass of 15.65 kg) is initially moving to the left with a speed of 2.26 m/s. The mass of m is 8.26 kg and the coefficients of friction are μs = 0.411 and μk = 0.304...
