A person with machine gun can fire 50 ~g bullets with a velocity of 240 ~m / s . A 60 ~kg tiger moves towards him with a velocity of 12 ~m / s . In order to stop the tiger in track, the number of bullets the person fires towards the tiger is

Options

  1. A50
  2. B60
  3. C70
  4. D80

Correct answer

B. 60

Step-by-step solution

In order to stop the tiger, the momentum of the bullets fired must be equal to the momentum of the tiger. array ll & MV = nmv & n = MV mV = 60 12 50 10⁻³ 240 & n =60 array
