Questions
A ball of mass m moving with a speed u undergoes a head - on elastic collision with a ball of mass nm initially at rest. The fraction of the incident energy transferred to the heavier ball is
detailed solution
Correct option is D
Let the velocities of the two balls, after collision be v1 and v2 is the direction of u which is taken as positive.mu=mv1+nmv2,e=1v2−v1=u,v2=2un+1,Fractional energy transferred=K.E.of ball of mass nmincident energy=12nm×2un+1212mu=4nn+12Talk to our academic expert!
