Items in parentheses are the solutions to the problem The 8-lb collar starts from rest at A under the action of the constant force P = 10 lb and slides alongthe rough fixed inclined rod in a vertical plane. If the speed of the collar as it passes position B is 3ft/sec, calculate the work done by the friction force between the collar and the rod. Use d = 4.5 ft,b = 2 ft, and 0 = 25°.
