A bullet is fired on a fixed target. It penetrates inside the target through distance d = 3.75 cm and then stops. mass of the bullet is m = 1 kg and of the target is M = 4 kg. Now an identical bullet moving with the same velocity is fired on the identical target which is placed at rest on a frictionless horizontal surface. Then find the distance (in cm) to which the bullet will penetrate inside the target?

N beads identical beads are resting on a smooth horizontal wire which is circular at the end with radius r=0.5m as shown in the figure. Find the minimum velocity which should be imparted to the first bead such that nth bead will fall in the tank after completing full circle in vertical plane as shown in the figure. Take all the collisions between the beads elastic (e = 1).

Two identical blocks P and Q have mass m each. They are attached to two identical springs initially unstretched. Now the left spring (along with P) is compressed by 2 A and the right spring (along with Q) is compressed by A. Both the blocks are released simultaneously. They collide perfectly inelastically. Initially time period of both the block was T. The time period of oscillation of combined mass is

Two masses A and B of 3 kg and 2 kg are connected by a long inextensible string which passes over a massless and frictionless pulley. Initially the height of both the masses from the ground is same and equal to 1 metre. When the masses are released. Mass A hits the ground and gets stuck to the ground. Consider the length of the string as large, so that the pulley does not obstruct the motion of masses A and B

A ball of mass m = 200 gm is suspended from a point A by an inextensible string of length L. Ball is drawn to a side and held at same level as A but at a distance root 3/2 L from A as shown. Now the ball is released. Then :( assume string applies only that much jerk which is required so that velocity along string becomes zero ).

The Fig. showns a string of equally placed beads of mass m, separated by distance. The beads are free to slide without friction on a thin wire. A constant force F act on the first bead initially at rest till it makes collision with the second bead. The second bead then collides with the third and so on. Supposed that all collisions are elastic,
