A pendulum of mass m_1 is released at an angle theta_1 and strikes the pendulum of mass m_2, which rises to angle theta_2. The coefficient of restitution e for the two masses is given. Derive an expression for the angle theta_2.
The Attempt at a Solution
Solving for v1 at time of impact using conservation of energy I get v1=Sqrt(2gl(1-cos(theta_1)))
I solve the same equation for v'2=sqrt(2gl(1-cos(theta_2)))
I then plug in the coefficient of restitution equation and solve for theta_2
My issue is determining whether or not this is a complete elastic collision. If so I assume the v'1 would be omitted, correct?
