Expert Solution
Step 1

Given thatmass of clay ball, m=0.25 kgmomentum of ball 1, P1=+1.75 kg.m/s      momentum of ball 2, P2=-1.75 kg.m/stotal momentum before collision=P1+P2                                                       =1.75-1.75                                                       =0 kg.m/s
