Two balls, of masses $m_A=44g$ and $m_B=63g,$ 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 $1)$

Part A

What is the velocity of the lighter ball before impact?

Express your answer using two significant figures.$\backslash$end$\{$array$\}]$

$\frac{m}{s}$

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.$\backslash$end$\{$array$\}]$

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.
