5.Imagine you are ice skating with your BFF. Both of you at rest, when you shove him/her away from you. You have a mass of 65 kg and he/she has a mass of 55kg. When you shove off, you move away with a velocity of 2.0 m/s. With what velocity does your BFF move away from you

v2 = 2.36 m/s

Explanation:

Momentum is simply the the product of mass of an object and it velocity. Generally, when object moves they have momentum . The unit for momentum is kgm/s.

During collision momentum is conserved . This means that

initial momentum = final momentum

If their is an equal and opposite reaction your momentum should be equal to your BFF.

m1 v1 = m2 v2

m1 = 65 kg

v1 = 2.0 m/s

m2 = 55 kg

v2 = ?

m1 v1 = m2 v2

65 × 2 = 55v2

130  = 55 v2

divide both sides by 55

v2 = 130/55

v2 = 2.36363636364

v2 = 2.36 m/s
