i have got the answer but i want to know a proper method

newtons law of motion will do it for you!

i used v^2 - u^2 = 2as

i just need to know what should i take for acceleration
or should i ignore it

u must find the acceleration dude....

Ok....Acceleration is negative since it is slowing down.....

ya sure

here v=u/2,and use the equation v^2=u^2-2as

then u will get accelration

then finally equate v=0,a=obtained from above and find s!!!

since here the question asked is "how much more will it penetrate" initial velocity=u/2...

i am getting a= -u^2/8

is dat right
?

yup..

yup....

there fore the equation for finding "s" should be|dw:1359144797548:dw| right

so i get s=1 cm

i got that too...

correection |dw:1359144893116:dw|

thnku all

your welcome....

yes.. i was wondering whats wrong. so s=4cm. it penetrates 1cm more.
