A 39.0 N force pulls horizontally on a m1 = 1.3 kg block that slides on a rough horizontal surface.

Two blocks of masses M1 = 3.5 kg and M2 = 5.7 kg are at rest on a horizontal surface with a coefficient of friction uk = 0.12. You start them moving by pushing on block 1 with a force F1H = 33 N at an angle of 42 degrees below the horizontal. The magnitude of kinetic friction force on each bock is f1 = 6.76 N and f2 = 6.70 N Determine the acceleration of the blocks and the magnitude of the normal force between the blocks.
A block M1 of mass 10.0 kg sits on top of a larger block M2 of mass 20.0 kg which sits on a flat surface. The kinetic friction coefficient between the upper and lower block is 0.440. The kinetic friction coefficient between the lower block and the flat surface is 0.140. A horizontal force F= 97 N pushes against the upper block, causing it to slide. The friction force between the blocks then causes the lower block to slide also. What is the magnitude of the acceleration of the upper block? What is the magnitude of the acceleration of the lower block?
block 1 of mass m1 2.0 kg and block 2 of mass m2 3.0 kg are connected by a string of negligible mass and are initially held in place. Block 2 is on a frictionless surface tilted at u = 30.

Once they are released, the blocks move.What then is the tension in the string?
A large wrecking ball of mass m is resting against a wall. It hangs from the end of a cable that is attached at its upper end to a crane that is just touching the wall. The cable makes an angle of θ with the wall. Ignoring friction between the ball and the wall, find the tension in the cable.
A block of mass m is sitting on a block of mass M. The bottom block is sitting on a horizontal floor.
