2. A 3.80-kg hanging block is pulling against a 2.50-kg block on a tabletop, as shown, via a string over a pulley that is massless and frictionless. At the same time, a constant external force F = 5.50 N is pulling the tabletop block to the right, as shown. There is a static friction coefficient is = 0.75, and kinetic friction coefficient dx = 0.15, with the tabletop. (a) The blocks are initially stationary. With a calculation, determine whether the...

Problem 3: Determine the acceleration of block B, acceleration of block A, and the tension in the cable if the system is released from rest. The coefficient of static and kinetic friction between block A and the wedge surface are js = 0.2 and uk = 0.15, respectively. Neglect masses of the pulleys and associated friction in the pulleys. Consider ma = 15 kg and mp = 8 kg. FBDs and kinetic diagrams for blocks A and B is mandatory....

Questions A 540-kg log is being steadily pulled up the incline by means of the cable attached to the winch on the truck. If the coefficient of kinetic friction is 0.68 between the log and the incline and 0.51 between the cable and rock, determine the tension which must be developed by the winch Answer: T- the tolerance is +/-2%

After rounding second base, a baseball player with a mass of 77 kg slides into third base. The coefficient of kinetic friction between the player and the ground is 0.42. What is the magnitude of the friction force acting on the player? If it takes 1.3 s for the player to come to a rest at the base, what was his velocity when he initiated his slide? Suppose you are pulling a 4.2-kg block across a rough, horizontal surface with...
