Homework Statement
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.
Homework Equations
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.[/B]
