Two people on ice skates push against each other. The person on the left is 50kg, the person on the right is 60kg. If the person on the right ends up going 3 m/s, how fast is the other person going?
This is for 8th grade physics on Newton’s 3rd law so pls nothing too complex

I got -3.6 m/s but I had to do conservation of momentum for this question. Which involves Newtons third law but with simply that law I do not know how to complete this question. If you would like me to post my work I will though! Sorry

The speed of the person on the left is 3.6 m/s.

Momentum of the skaters

The momentum of each skater is given as follows;

m₁v₁ = m₂v₂

where;

  • m₁ is mass of the person on the right
  • m₂ is mass of the person on the left
  • v is the speed of the skaters

Speed of the person on the left

The speed of the person on the left is determined by applying the principle of conservation of linear momentum;

50v₁ = 60x3

50v₁ = 180

v₁ = 180/50

v₁ = 3.6 m/s
