Two identical blocks each having a mass of 20 kg are connected to each other by a light inextensible string as shown and as placed over a rough surface. Pulle
Two blocks of mass 2.9 kg and 1.9 kg are suspended from a rigid support S by two inextensible wires each of length 1 meter, see fig. The upper wire has negligible mass and the lower wire has a uniform mass of 0.2kg/m. The whole system of blocks wires and support have an upward ac...
A 1.0 kg block is moving to the right at 1.0 m/s just before it strikes and sticks to a 2.5 kg block initially at rest. What is the total momentum of the two blocks after the collision? Two cars of equal mass collide inelasti...
