A 60 kg tiger springs at hunter with a velocity of `10 m//s` the hunter possesses a machine gun that can fire 50 g bullets with a velocity of `150 m//s`. the hunter can save himself from the tiger by firing suitable number of bullets/sec into the tiger.read the above passage and answer the following questions:
(i) What principal is involved here?
(ii) How many bullets/sec. must the hunter fire into the tiger?
(iii) What lessons do you learn from this?

Explanation

(i)The principle involved here : rate of change of linear momentum of bullets = rate of change of linear momentum of tiger.
(ii) If n bullets/sec are fired, then
`nxx(50xx10^(-3))xx150=60xx10`
`n=(60xx10)/(50xx150xx10^(-3))=80`
(iii) If you encounter such a sutuation, you have to be real fast. pump as many bullets as you can into the the tiger in shortest possible time.
