Frictionless track

Determine:

$($a$)$ The maximum velocity of block C $(10$ pts$)$

$($b$)$ Discuss the role of the frictionless track effect in the velocity result. What would change if there were friction? $(10$ pts$)$

$($c$)$ What is block C$\text{'}$s velocity immediately after the bullet's impact? $(2$ pts$)$
