Sean, who has a mass of 65-kg, is out roller
blading with friends at a speed of 3 m/s. Not
realizing he accidentally let the dog out as he
was leaving, Sean finds his 12-kg pup at rest in
the middle of the street. Sean gracefully scoops
the dog up as he skates down the road and
proceeds to carry the pup home. Calculate their
final velocity

Respuesta :

The final velocity will be 2.53 m/sec. Apply law of conservation of momentum principle in given problem.

What is the law of conservation of linear momentum?

According to the law of conservation of linear momentum before the collision is equal to the momentum after the collision. These laws state that about how momentum gets conserved.

Apply law of conservation of momentum principle;

m₁v₁+m₂v₂=(m₁+m₂)V

65 kg×3 m/s+12 kg×0 m/s=(65 kg+12 kg)*V

V=2.53 m/sec.

Hence, the final velocity will be 2.53 m/sec.
