A bullet of mass 20gram strikes a target with a velocity of 100m`//`s and is brougth to rest after piercing 20cm into it. What is the average force of resistance offered by the target?

A bullet of mass 10g strikes a fixed target and penetrates 8 cm into it before coming to rest. If the average force of resistance offered by the target is 100 N with what velocity does it strike ? :

A bullet of mass 0.1 kg moving horizontally with a velocity of 20 m//s strike a stationary target and is brought to rest in 0.1 s. Find the impulse and average force of impact.

A bullet of mass 10 gm moving with a velocity .u. penetrates 4 cm in to a target before coming to rest. If the average resistance offered by the target is 200 N, the value of .u. is

A bullet of mass 20gm is fired from a riffle of mass 8 kg with a velocity of 100m//s . The velocity of recoil of the rifle is

A bullet of mass 20 g is fired with a velocity of 1000 m/s . After passing through a mud wall 1.5 m thick , its velocity decreases to 400 m/s . Calculate the average resistance offered by the mud wall .

A 10.0-g bullet traveling horizontally at 755 m/s strikes a stationary target and stops after penetrating 14.5 cm into the target. What is the average force of the target on 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.
