A bullet travellling with a velocity of 16 m/s penetrates a tree trunk and comes to rest in 0.4 m. Find the time taken during the retardation.

. A bullet moving with a velocity of 200 cm / s penetrates a wooden block and comes to rest after traversing 4 cm inside it. What velocity is needed for travelling distance of 9cm in same block

A bullet moving with an initial velocity of 20 m s^(-1) , strikes a target and comes to rest after penetrating the target to a distance of 10 cm. Calculate the retardation caused by the target.

A bullet of mass 0.1Kg moves with velocity 10 m/s it strikes a block and comes to rest after travels 0.5 m inside block. Find retardation of bullet

A bullet of mass 10g travelling horizontally with a velocity of 150 ms^(-1) strikes a stationary wooden block and come to rest in 0.03 s . Calculate the distance of penetration of the bullet into the block. Also, Calculate the magnitude of the force exerted by the wooden block on the bullet,

A particle accelerates from rest at a constant rate for some time and attains a velocity of 8 m/sec. Afterwards it decelerates with the constant rate and comes to rest. If the total time taken is 4 sec, the distance travelled is
