Question

a block of mass m moving with velocity vo collides with another stationary block

Answer 1

Using law of law of conservation of linear momentum, we get

Using law of law of conservation of linear momentum, we getmv=4mv′

Using law of law of conservation of linear momentum, we getmv=4mv′velocity of block having mass 4m,v′=v/4

Using law of law of conservation of linear momentum, we getmv=4mv′velocity of block having mass 4m,v′=v/4e=vv/4=0.25

hope it helps
