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 ?
anonymous
  • anonymous
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
anonymous
  • anonymous
\[V^2 - u^2 = 2as\] \[\frac{ 150*150*100 }{ 2*10 } = a\]

\[F= Ma\]

if u find the acceleration, then u can calculate the average resistance force by multiplying acceleration with mass
anonymous
  • anonymous
Note mass shuld be in kg 1 gm = 10^-3 kg
anonymous
  • anonymous
no need to calculate change in the momentum
