Two balls, of masses $m_A=46g$ and $m_B=69g,$ are suspended as shown in the figure. The lighter ball is pulled away to a $66$ angle with the vertical and released. Assume that the positive $x$ axis is directed to the right. $($Figure $1)$

What is the velocity of the lighter ball before impact?

Express your answer using two significant figures.

$v_A=,\frac{m}{s}$

Part B

What is the velocity of each ball after the elastic collision?

Express your answers using two significant figures. Enter your answers numerically separated by a comma.

$\sqrt[n]{}A$

Part C

What will be the maximum height of each ball after the elastic collision?

Express your answers using two significant figures. Enter your answers numerically separated by a comma.
