1. The problem statement, all variables and given/known data Two spheres of mass M1 and M2 are arranged one above the other as shown. They are separated by a fraction of a mm. They are released from rest and allowed to fall to the ground, a distance h = 5.0 m below. Mass M2 collides elastically with the ground and then elastically with mass M1. Calculate the maximum height the center of M1 rises above the ground after the collision. D = 0.20 cm, d = 0.05 cm, M1 = 0.20 kg, M2 = 1.10 kg. 2. Relevant equations 3. The attempt at a solution so I got the velocity by using vf^2 = 2ad and got 9.89m/s. I use the collision formula: (9.89)(1.1)=(.2)(v) v= 54.337 - 9.89 =44.557 m/s for the smaller ball. then 0=44.557^2+2ad d=101.29 + 5 m = 106m. Its incorrect.
