A bullet of mass `2 g` travelling at a speed of `500 m//s` is fired into a ballistic pendulum of mass `1.0 kg` suspended from a cord `1.0 m` long. The bullet penetrates the pendulum and emerges with a velocity of `100 m//s`. Through what vertical height will the pendulum rise?

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 bullet of mass 10g is fired from a rifle. The bullet takes 0.003 seconds to move through its barrel and leaves with a velocity of 300m/s. What is the force exerted on the bullet by the rifle?

A bullet of mass 10 g moving with velocity v becomes embedded in a ballistic pendulum of mass 2kg. The pendulum rises to a height of 10 cm. Find velocity of bullet and energy lost in collision.

A bullet of mass 0.01 kg travelling at a speed of 500 m/s strikes a block of mass 2 kg, which is suspended by a string of length 5 m. The centre of gravity of the block is found to rise a vertical distance of 0.1 m. The speed of the bullet after it emerges from the block will be -

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.

A bullet of mass 100 g is fired by a gun of 10 kg with a speed of 2000 m/s find recoil velocity of gun
