A bullet of `10g` strikes a sand bag at a speed of `10^(3)m//s` and gets enbedded after a travelling `5 cm`. Calculate
(i) the resistive force exerted by sand on the bullet
(ii) the time taken by the bullet to come to rest.

Using second law of motion, derive the relation between force and acceleration. A bullet of 10g strikes a sand-bag at a speed of 10^(3)ms^(-1) and gets embedded after travelling 5cm .Calculate (i) the resistive force exerted by the sand on the bullet (ii) the time taken by the bullet to come to rest.

A 20 gram bullet moving at 300m//s stops after penetrating 3cm of bone. Calculate the average force exerted by the bullet .

A bullet of mass 0.06 kg moving with a speed of 90ms^(-1) enters a heavy wooden block and it stopped after a distance of 60 cm. What is the average resistive force exerted by the block 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 stooped after a distance of 60 cm . What is the average resistive force exerted by the block on the bullet ?

A bullet of mass 0.03 kg moving with a speed of 400m/s penerates 12 cm into fixed block of wood. Calculate the average force exerted by the wood on the bullet.

A bullet of mass 5 g travels with a speed of 500m/s. If it penetrates a fixed target which offers a constant resistive force of 1000N to the motion of the bullet, find (a) the initial kinetic energy of the bullet (b) the distance through which the bullet has penetrated.

A bullet of mass 20 g moving with a speed of 120 m/s hits a thick muddy wall and penetrates into it. It takes 0.03 s to stop in the wall find the force exerted by the bullet on the wall,
