If a bullet of mass 5 g moving with avelocity of `100m//s` penetrates a wooden block upto 6cm . Find the average force imposed.

Text Solution

Verified by Experts

`u=100 m//s , v=0, S = 6xx10^(-2)m, a=? , v^(2)-u^(2)=2as`
`0^(2)-(100)^(2)=2xxaxx6xx10^(-2)`
`a=(-100xx100)/(2xx6xx10^(-2)), a=-1/(12)xx10^(6) m//s`
`F=ma =5xx10^(-3)xx[-1/(12)xx10^(6)],F= (-5000)/(12)=-417 n`
Retarding force F=417 N
