Question

a body of mass M and energy collides elastically with the mass 2m at the rest. the change in kinetic energy of a mass M is​

Answer 1

Answer:

Dear pragati ,

The coefficient of restitution is given by

e=vfb−vfavia−vibWhere f and i represents final and initial velocities respectivelyhere vib=vfa=0From conservation of momentummv=2mv'v'=v/2e=v/2−0v−0e=12
