Expert Solution
Step 1

Given masses and their velocities are:

m1 =2.5 kg;   v1= 2 m/sm2 =1.5 kg;   v2 = 1 m/sm3 =0.97 kg;  v3= -0.37 m/sm4 = 0.94 kg; v4= -0.44 m/s

By the law of conservation of momentum Total momentum before collision equals total momentum after collision

as all the masses stick together during collision so :

m1v1+m2v2+m3v3+m4v4 = (m1+m2+m3+m4)v
