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-s

B

zero

C

0.9N-s

D

1.8N-s

Text Solution

Verified by Experts

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