The arrangement shown in the diagram is moving in space with an acceleration a=4(hati+hatj)m//s^(2). An ideal spring of natural length l_(0) having spring constant k=50 N//m, is connected to block A. Blocks A and B are connected by an ideal string passing through a frictionless pulley. Mass of each block A and B is equal [...]

A spring mass system is held at rest with the spring relaxed at a height (h) above the ground. Determine the minimum value of (H) so that the systen has a tendency to rebound after hitting the ground. Given that the coefficient of restitution between (m_(2)) and ground is zero. B and C is 1/2. [...]

Two blocks of masses of 0.2 kg and 0.5 kg which are placed 22m apart on a horizontal surface (mu = 0.5) are acted uponby two forces of magnitude 3 Neach as shown in figure in time t = 0 Then the time t at which they collide with each other is B and C [...]

Two blocks of masses of 0.2kg and 0.5kg which are placed 22m apart on a horizontal surface (μ=0.5) are acted uponby two forces of magnitude 3Neach as shown in figure in time t=0 Then the time t at which they collide with each other is B and C is 1/2. the maximum value of mass [...]

Three blocks A,B and C of equal mass m are placed one over the other on a smooth horizontal ground as shown in figure. Coefficient of friction between any two blocks of A,B and C is 1/2. the maximum value of mass of block D so that the blocks A,B and C move without slippping [...]
