A bullet of mass 25 g moving with a speed of 100 m/s pierces a bag full of sand kept adjacent to a wall. The bullet stops in the bag after 0.05 second. Find The acceleration of the bullet (assuming uniform).

A bullet of mass 25 g moving with a speed of 100 m/s pierces a bag full of sand kept adjacent to a wall. The bullet stops in the bag after 0.05 second. Find The force exerted by the sandbag on the bullet.

A bullet of mass 0.04 kg moving with a speed of 90 ms^-1 enters a heavy wooden block and is stopped after a distance of 60 cm. What is the average resistive force exerted by the block on the bullet?

A bullet of mass 20 g is fired with speed 400 m s^-1 by a gun of mass 8 kg. Find the recoil velocity of the gun.

A bullet of mass 20 g moving with a speed of 500ms^(-1 ) strikes a wooden block of mass 1 kg and gets embedded in it. Find the speed with which block moves along with the bullet.

A bullet of mass 40 g hits a mud wall with speed 400 m s^-1 . The bullet stops after penetrating 50 cm inside the wall. Find the average resistive force exerted by the wall on the bullets.

A bullet (m_1 = 25 g) fired with a velocity of 400m//s gets embedded into a bag of sand (m_2 = 4.975 kg) suspended by a rope.The velocity gained by the bag is nearly:

A bullet of mass 0.012 kg and horizontal speed 70 m s^-1 strikes a block of wood of mass 0.4 kg and instantly comes to rest with respect to the block. The block is suspended from the ceiling by means of thin wires. Calculate the height to which the block rises. Also, estimate the amount of heat produced in the block.
