Questions
A bullet of mass 10-3kg strikes an obstacle and moves at 60° to its original direction. If its speed also changes from 20 m/s to 10 m/s , the magnitude of the impulse acting on the bullet is
detailed solution
Correct option is D
Ix=10−320−10cos 60∘N−S=15×10−3N−S=15×10−3N−SIy=10−3×10sin 60∘N−S=53×10−3N−S∴I=Ix2+Iy2=3×10−2N−S.Talk to our academic expert!
