    Momentum question involving an elastic collision

    I fixed it. When I solve it I get -0.7366 and -5.6195 for v1 but neither of those are answers.

    Momentum question involving an elastic collision

    Kinetic energy is also conserved. This is all the work I have done so far. (62)(2.8) + (76)(1.6) = 62v1 + 76v2 0.5(62)(2.8)^2 + 0.5(76)(1.6)^2 = 0.5(62)(v1)^2 + 0.5(76)(v2)^2 295.2 = 62v1 + 76v2 and 340.32 = (31)(v1)^2 + (38)(v2)^2 v2= (295.2 - 62v1)/76 340.32 = (31)(v1)^2 +...

    Momentum question involving an elastic collision

    1. A 62 kg skater traveling at 2.8 m/s accidentally bumps elastically into a 76 kg skater moving at 1.6m/s in the same direction Find the velocity of each skater after the collision 2. m1v1 + m1v2 = m1v3 + m2v4 3.
