    5. Two boxes are connected by a rope over a pulley. Box A is on a horizontal surface and box B hangs off vertically from the pulley at the edge of the surface A is on. Let the masses of these boxes be mA 5kg and m 2k9. Assume that the mass of the rope and the pulley, and the friction of the pulley is negligible. The coefficient of kinetic friction is μ.-0.2 between box A and the table. Find...

    You pull a box 45 degrees from the horizontal with 50N force. The box is moving at a constant velocity. How much force is done by the kinetic friction? For any problems with tensions, pushing or moving boxes, draw out a free body diagram. You only want the kinetic frictional force which is only on the x direction, so let's sum up the forces in the x Fr=maio (28)

    2. A box (M-8.5 kg) sits on a table (box #1). Another box (m=6.3 kg) sits on a ramp at an angle of e= 30° (box #2). The boxes are connected to each other with a cable and pulley, as shown in the diagram to the right. The static coefficient of friction between box #1 and the table is 0.88, and the kinetic coefficient is 0.81. There is no friction between box # 2 and the ramp. (4 pts.) Draw...

    Need help with the whole problem. Thank you! Even if the problem comes with a figure, draw your own set-up. Identify the key points on your drawing: those would be the center of the objects, or the knots of the ropes - if ropes are connected to each other. Once you identified those points place an xy system of coordinators in each of them, so that one of the axis points in the direction of the motion, or in the...

    Dynamics, please answer all parts.Thank you Given: Block A has a known constant mass of mA and block B has a known constant mass of ms. The coefficient of kinetic friction between block A and the incline is ex. Both block masses should be considered in your analysis, but the mass of block A is large enough so that block A slides down the incline after starting from rest. You may neglect the masses of the pulleys and cable. It...
