Questions
A body of mass M moving with velocity v undergoes a head on collision with a body of mass m moving with the same velocity but in opposite direction. If the two body stick together after the collision, the speed of the common body will be
detailed solution
Correct option is C
. The total momentum before collision = (M-m)vMomentum after collision = (M+m) Vwhere y is the speed on composite body. Applying the law of conservation of momentum, we have(M+m)V=(M−m)v V=M−mM+mvTalk to our academic expert!
