Determine the acceleration of the 5 kg block A . Neglect the mass of the pulley and cords . The block B has a mass of 10 kg , The coefficient of kinetic friction between block B and the surface is mu _(k) = 0.1 (take g = 10 m//s^(2))

A granite block in the shape of a right rectangular prism has dimensions 30 centimeters by 40 centimeters by 50 centimeters. The block has a density of 2.8 grams per cubic centimeter. What is the mass of the block, in grams? (Density is mass per unit volume.)

The block of mass m is kept on plank of mass M. The block is given velocity V_(0) as shown. The coefficient of friction between the block of mass m and plank of mass M is mu and its value is such that block becomes stationary with respect to plank before it reaches the other end. Then:

The block of mass m is at rest. Find the tension in the string A .

A block B is placed over a cart which in turn lies over a smooth horizontal floor. Block A and Block C are connected to block B with light inextensible strings passing over light frictionless pulleys fixed to the cart as shown. Initially the blocks and the cart are at rest. All the three blocks have mass m and the cart has mass M(M=3m) . Now a constant horizontal force of magnitude F is applied to block A towards right. Q. Let the coefficient of friction between block B and cart is mu(mugt0) and friction is absent everywhere else. Then the maximum value of force F applied to block A such that there is no relative acceleration between block B and cart is

Three blocks are initially placed as shown in the figure. Block A has mass m and initial velocity v to the right. Block B with mass m and block C with mass 4m are both initially at rest. Neglect friction. All collisions are elastic. The final velocity of blocks A is

Three blocks are placed on smooth horizontal surface and lie on same horizontal straight line. Block 1 and block 3 have mass m each and block 2 has mass M (M gt gt m) . Block 2 and block 3 are initially stationary, while block 1 is initially moving towards block 2 with speed v as shown. Assume that all collisions are head on and perfectly elastic. What value of M//m ensures that block 1 and block 3 have the same final speed?

There are two blocks A and B placed on a smooth surface. Block A has mass 10 kg and its is moving with velocity 0.8 m/s towards stationary B of unknown mass. At the time of collision, their velocities are given by the following graph : Maximum deformation potential energy is :
