GO Figure 5-47 shows two blocks connected by a cord (of negligible mass) that passes over a frictionless pulley (also of negligible mass). The arrangement is known as Atwood’s machine. One block has mass m1 = 1.30 kg; the other has mass m2 = 2.80 kg. What are (a) the magnitude of the blocks’ acceleration and (b) the tension in the cord?

Block A ( mass 2.25 kg) rests on a tabletop. It is connected by a horizontal cord passing over a light, frictionless pulley to a hanging block B ( mass 1.30 kg). The coefficient of kinetic friction between block A and the tabletop is 0.450 .
After the blocks are released from rest , find (a) the speed of each block after 3.00 cm and (b) the tension in the cord
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.
The figure shows a container of mass m1 = 4.4 kg connected to a block of mass m2 by a cord looped around a frictionless pulley. The cord and pulley have negligible mass. When the container is released from rest, it accelerates at 1.3 m/s2 across the horizontal frictionless surface. What are (a) the tension in the cord and (b) mass m2?

One end of the plank is slowly raised to make it more and more inclined, and for a while the block stays in place on the plank and doesn't slide due to static friction.
