A large mass M = 9.00 kg hangs from a massless rope that is connected to a box, m = 5.00 kg. The rope passes over a massless pulley and does not stretch. Due to the hanging mass, the box is accelerated along the surface to the left.a) Draw free-body diagrams for the mass, M, and the box, m. Indicate xy-coordinate directions for each object. Indicate the direction of positive acceleration. b) If the acceleration of the box is 5.50 m/s2 determine the coefficient of kinetic friction µk between the box and the table surface.

A simple elevator ride can teach you quite a bit about the normal force. There are three different scenarios given detailing the rider's experience in an unnamed hotel. For each scenario, calculate the normal force FN,1-3 acting on the rider if his mass is m = 72.1 kg and the acceleration due to gravity g = 9.81 m/s?. In scenario 1, the elevator has constant velocity. FN.1 N Constant velocity Scenario 1
1) The block on a 60° inclined plane weighs 100 pound and is held by the minimum possible force T as shown in the figure. The coefficient of both static and kinetic friction between the block and the inclined plane is 0.2, and the pulleys are frictionless. T а. Draw the free body diagram (FBD) of the block showing all forces and their directions acting on it. b. Compute all unknown forces including T shown in your FBD. Now if you want to move the block upward on the inclined plane С. by applying minimum possible force T then draw the FBD of the block showing all forces with directions acting on it. d. Now assume the pulleys are stuck (do not rotate any more) and the 60° rope slides over the stuck pulleys as the block moves up. the coefficient of both static and kinetic friction between the pulley surface and the rope is 0.1. Draw the FBD of the block showing all forces with directions acting on the block when the block is pulled upward by the minimum rope force T. е. For the stuck…
