MHT CET 2023 Physics question
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
Answer: (B)
Solution
To stop the tiger, the total momentum of the bullets fired at it (and stopping in it) must equal the tiger's momentum, so that the net momentum is zero. Tiger's momentum: . Momentum of one bullet: $0.05×240=12\
