A bullet travelling horizontally looses `1//20^(th)` of its velocity while piercing a wooden plank. Then the number of such planks required to stop the bullet is

A bullet loses 1//2th1 of its velocity is passing through a plank. What is the least number of planks required to stop the bullet ?

A bullet looses ((1)/(n))^(th) of its velocity passing through one plank.The number of such planks that are required to stop the bullet can be:

A bullet loses 1//20 of its velocity in passing through a plank. What is the least number of plank required to stop the bullet .

A bullet losses 1/6 of its velocity in passing through a plank. What is the least number of planks required to stop the bullet ?

A bullet loses 1//20 of its velocity on passing through a plank. What is the least number of planks that are required to stop the bullet ?

A bullet losses 1/n of its velocity in passing through a plank. What is the least number of plancks required to stop the bullet ? (Assuming constant retardation)
