Two 100 g blocks hang at the ends of a light flexible cord passing over a small frictionless pulley. A 40 g block rests on the block an right and removed after 2 sec. (a) How far will each block move in the first second after the 40 g block is removed? (b) What was the tension in the cord before the 40 g block was removed? (c) What was the tension in the cord supporting the pulley after the 40 g block was removed?

A 10 kg block is connected to a 40 kg block as shown in the figure. The surface on that the blocks slide is frictionless. A force of 50 N pulls the blocks to the right. What is the magnitude of the tension T in the rope that connects the two blocks?

A 10 kg block is connected to a 40 kg block as shown in the figure. The surface on that the blocks slide is frictionless. A force of 50 N pulls the blocks to the right. What is the magnitude of the acceleration of the 40 kg block ?

A block of mass m is at rest on an another block of same as shown in figure lower block is atteched to the spring than the maximum amplitude of motion as than both the block will remain as mat both the block will remain in contact is
