Consider the situation as shown in the diagram. The bullet penetrates the block and emerges with speed `v_(0)//3`. If after collision , the string becomes horizontal , `v_(0)` will be

In the previous problem , the bullet penetrates the block and emerges with speed v_(0) .If the block travels 2.5 m on the rough surface , the value of v_(0) is

Consider the situation as shown in the diagram. The coefficient of friction between the block is 0.5 . The acceleration of the lower block is

Consider the situation shown in the figure. The surface is smooth and the string and the pulley are light. Find the acceleration of each block and tension in the string.

A bullet of mass 10 kg moving horizontally at a speed 140 m//s strikes a block of mass 100 g attached to a string like a simple pendulum. The bullet penetrates the block and emerges on the other side. If the block rises by 80 cm , find final velocity of bullet.

Consider the situation as shown. If a vehicle moves towards right with constant velocity v_(0) , find the velocity and acceleration of the block in terms of h and x, where x is the distance traveled by the vehicle towards right.

A bullet of mass 20 g moving horizontally at a speed of 300 m/s is fired into a wooden block of mass 500 g suspended by a long string. The bullet crosses the block and emerges on the other side. If the centre of mass of the block rises through a height of 20.0 cm, find the speed of the bullet as it emerges from the block.

A pendulum consists of a wooden bob of mass M and length l . A bullet of mass m is fired towards the pendulum with a speed v . The bullet emerges immediately out of the bob from the other side with a speed of v//2 and the bob starts rising. Assume no loss of mass of bob takes place due to penetration. If the bob stops where the string becomes horizontal then v is
