Three blocks are in contact on a frictionless, horizontal table top.

Two blocks with masses m1 = 24.8 kg and m2 = 79.8 kg, shown in the figure, are free to move. The coefficient of static friction between the blocks is 0.60 but the surface beneath m2 is frictionless. What is the minimum force F required to hold m1 against m2?

Three blocks rest on a frictionless tabletop and are connected by strings as shown. The blocks have masses m1 = 2.25 kg, m2 = 3.85 kg, and m3 = 1.61 kg. You can neglect the mass of all strings in this problem. A rightward force of F = 23.9 Newtons is exerted on block 3. Calculate the tension T1 in Newtons.  Calculate the tension T2 in Newtons.

Three people pull simultaneously on a stubborn donkey. Jack pulls directly ahead of the donkey with a force of 98.1 N, Jill pulls with 90.7 N in a direction 45° to the left, and Jane pulls in a direction 45° to the right with 115 N. (Since the donkey is involved with such uncoordinated people, who can blame it for being stubborn?) Find the magnitude of the net force the people exert on the donkey. magnitude of the net force: What is the direction of the net force? Express this as the angle from straight ahead between 0° and 90°, with a positive sign for angles to the left and a negative sign for angles to the right. direction of the net force:

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.
