Homework Statement
A block of mass m1 = 5.00 kg is released from A. It makes a head on elastic collision at B with a block of mass m2=10.0kg that is initially at rest. Calculate the maximum height to which m1 rises after the collision
Homework Equations
Pi = Pf
Ef= Ei + other work
The Attempt at a Solution
1/2 m1v1^2 = m1gh
v1 = square root of 2gh = 10 m/s
Pi = Pf
m1v1 +m2v2 = m1c1 + m2c2
m1v1 = m1c1 + m2c2
m1(v1 - c1) = m2c2
1/2 m1v1^2 = 1/2 m1c1^2 + 1/2 m2c2^2
m1(v1^2 - c1^2) = m2c2^2
then i used that and divided by the Pi = Pf and i got
(v1+c1) = c2
all right I'm stuck around here and have no clue what to do from here. Someone help me please?
