Two blocks

A block of mass m is pressed against a wall which is moving with an acceleration a as shown in Fig. 7.250. If the block is pulled at an angle theta with downward vertical by a force F and it does not slide are stacked as shown in Fig. 7.241 and placed on a frictionless [...]

Four blocks are arranged on a smooth horizontal surface as shown in Fig. 7.249. The masses of the blocks are given (see the figure). The coefficient of static friction between the top and the bottom blocks is mu s. are stacked as shown in Fig. 7.241 and placed on a frictionless horizontal surface. There is [...]

Two blocks, with masses m1 and m2, are stacked as shown in Fig. 7.241 and placed on a frictionless horizontal surface. There is a friction between the two blocks. An external force of magnitude F is applied are stacked as shown in Fig. 7.241 and placed on a frictionless horizontal surface. There is a friction [...]

Two blocks, of mass 1 kg and 2 kg respectively, are connected by a spring and kept on a frictionless table. The blocks are pulled apart, so that the spring is stretched, and released from rest. At a certain instant of time, the block of mass 1 kg, is found to be moving at a [...]
