Question

A body of mass 2 kg, initially moving with a velocity of 10 m/s, collides with another body of mass 5 kg at rest. after collision velocity of first body becomes 1 m/s. find the velocity of second body.

Answer 1

momentum is to be conserved
2(10) + 5(0) = 2(1) + 5(v)
20=2+5v
18=5v
v=3.6 m/s

Answer 2

Answer:Momentum is to be conserved

2(10)+5(0)=2(1)+5(v)

20=2+5v

18=5v

v=3.6 m/s
