Questions
A particle of mass m kg moving with a velocity collides with a stationary body of mass M kg and finally moves with a velocity . If then
detailed solution
Correct option is D
m(3i^+2j^)=m(-2i^+j^)+Mv∴ v=(5i^+j^)13 ms-1 (put, M=13m)Impulse, Jm=pf-pi=±m[(-2i^+j^)-(3i^+2j^)]∴ Jm=±m(5i^+j^)kg·ms-1Talk to our academic expert!
