WebAfter the hit, the players tangle up and move with the same final velocity. Therefore, the final momentum, pf, must equal the combined mass of the two players multiplied by their final velocity, ( m1 + m2) vf, which gives you the following equation: ( m1 + m2) vf = m1vi1. Solving for vf gives you the equation for their final velocity: WebApr 10, 2024 · If the coefficient of restitution is e, then. v 2 −v 1 =−e(u 2 −u 1). This formula is Newton's law of restitution.
