Homework Statement
If it is eg. two balls, both going to the right before and after an elastic shock, how do you determine their velocities after the collision? (speeds before and weights are given)
Eg.
M = 50 kg
u1 = 20 m / sm = 100 kg
v1 = 10 m / s
(M, m = mass)
(u1, v1 = velocity before the collision)
(u2, v2 = velocity after collision)
Homework Equations
The law of conservation of momentum:
m*v1+M*u1= m+M*v2*u2
Momentum before = Momentum after
The Attempt at a Solution
m*v1+M*u1= m+M*v2*u2 →
100 * 10 +50 * 20 = 100 +50 * v2 * u2
How do I continue from here?
