WebDec 15, 2024 · If up is positive, the acceleration is -9.81m/s 2, and the distance is -9.02m. That way you get a positive Δ (v 2 ). Secondly, you cannot go straight from v f2 -v i2 to v f -v i by square rooting. You need to plug in the value for v i (0) first. Now you need to find the rebound speed by the same method. 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: edwisor.inWebMay 18, 2016 · inelastic impact.
