find out the change in momnetum
then average force of resistance= rate of change of momentum= (change in momentum)/ (time interval)

so 1st u have to calculate..how much time bullet will take in coming to rest?
does it make sense?
i guess i dont understand , sorry akash am slow in this , and i want you to help me , how to calculate change in momentum ?
change in momentum= (final momentum- initial momentum)
1st find accl
i mean... 1st the bullet was moving with a speed of 150m/s then its momentum = m(150), m=20g
yes use the formula v^2- u^2= 2as
\[V^2 - u^2 = 2as\] \[\frac{ 150*150*100 }{ 2*10 } = a\]
\[F= Ma\]
if u find the acceleration, then u can calculate the average resistance force by multiplying acceleration with mass
Note mass shuld be in kg 1 gm = 10^-3 kg
no need to calculate change in the momentum
hope this helps
According to COD ...this is maths page...and u r asking physics...Question....Plzzz...Go..to physics page
okay let me try , @akash123 and @Yahoo! thank yu !
am sry i din see that .. am sry !
