Question 4

When the 3 boxes in the Figure are released resting From state They are accelerated by meter of acceleration 0. 50 0m /52 in The direction shown in the drawing. The First 60 x x48 has mass M. the second has 2M and The third has mass 2 M. the pulleys are smooth and weightless. a) draw the released body diagram For all 3 bodies 6) what is the coefficient of friction Kinetic between cube 3 2 and the table? () if M= IKa determine the tension on the two ropes d) in the case the surface of the table is smooth The stresses on the two ropes will increase, decrease Of remain the same? explain. 2 1 3
