Questions
Two objects of mass m each moving with speed collide at 90°, then final momentum is (assume collision is inelastic) [JIPMER 2019]
detailed solution
Correct option is C
Speed of objects = u ms-1Since, both objects collide at 90°.Hence, by the law of conservation of momentum,Total momentum before collision = Total momentum after collision |mui^+muj^|=pf m2u2+m2u2=pf⇒ pf = 2 muTalk to our academic expert!
