A 75 kg Spider Man running at 3.0 m/s jumps onto a trash can lid that has a mass of 10kg and that is already moving in the same
direction as Spiderman, at 2.0 m/s. What will be the final velocity of Spiderman and the lid assuming that the lid is on a level slick surface and that there is no friction?
In order to find the final velocity of the skier and the trash can lid, we may apply the principle of conservation of momentum, which states that the total momentum of a system remains constant. Mathematically, in this case: m₁v₁ + m₂v₂ = m₃v₃ Where m₃ and v₃ are the combined mass and velocity.
