A bullet is fired from a gun. The force on the bullet is given by `F=600-2xx10^(5)` t, where F is in newtons and t in seconds. The force on the bullet becomes zero as soon as it leaves the barrel. What is the average impulse imparted to the bullet?A. 9N-sB. zeroC. 0.9N-sD. 1.8N-s |

Answer» F`=600-2xx10^(5)t=0` t`=(600)/(2xx10^(5))=3xx10^(-3)s` Impulse `=int_(0)^(1)` Fdt |
