It is known that the 10 kg pipe will roll up the ramp and not slide on the ramp when P becomes sufficiently large. Using the rolling assumption, find the minimum P required to cause impending motion of the 10 kg pipe up the ramp. Note that the coefficients of friction for the block/ramp, the pipe/ramp and the pipe/block contacts are each 0.30. 18 kg block 35° 10 kg pipe B μg 0.30 for all contacts

In the figure below, m, = 10.2 kg and m, = 4.3 kg. The coefficient of static friction between m, and the horizontal surface is 0.50, and the coefficient of kinetic friction is 0.30. An illustration shows a rectangular block of mass m, on the horizontal surface of a table. This is connected to another rectangular block of mass m, by a cord that runs over a pulley placed diagonally at the corner of the horizontal surface of the table. The rectangular block of mass m, is suspended vertically by the side of the tabletop. (a) If the system is released from rest, what will its acceleration be? (Enter the magnitude of the acceleration.) m/s? (b) If the system is set in motion with m, moving downward, what will be the acceleration of the system? (Enter the magnitude of the acceleration.) m/s2
