The velocity of a bullet is reduced from `200 m//s` to `100 m//s` while travelling through a wooden block of thickness `10 cm`. The retardation, assuming it to be uniform, will be.

(a) If a train traveling at 72 km//h is to be brought to rest in a distance of 200 m , find the deceleration. (b) The velocity of a bullet is reduced from 200 m//s to 100 m//s while traveling through a wooden block of thickness 10 cm . Find the retardation (assuming it ti be uniform).

The velocity of a bullet is reduced from 400 ms^(-1) to 100 ms^(-1) while travelling thought material of thickness of 1 m. The retardation will be

The velocity of a bullet is reduced from 400 ms^(-1) to 100 ms^(-1) while travelling thought material of thickness of 1 m. The retardation will be

A bullet of mass 10 g and velocity 800 m/s is passed through a mud wall of thickness 1 m . Its velocity reduces to 100 m/s . Find the average resistance offered by the mud wall.

A bullet of mass 10gm moving with a horizontal velocity 100m//s passes through a wooden block of mass 100gm . The block is resting on a smooth horizontal floor. After passing through the block the velocity of the bullet is 10m//s the velocity of the emerging bullet with respect to the block is .

If a bullet of mass 5gm moving with velocity 100m//sec, penertates the wooden block upto 6cm. Then the average force imposed by the bullet on the block is
