## Homework Statement

A block of mass m = 1.5 kg is launched from point A with speed VA = 12 m / s, in the circuit

shown in Figure 4. If we assume that there is no friction determine:

a) the speed of the block when it reaches the point C;

## Homework Equations

This question has about 10 questions but I only want to really understand the first one and I would like your help with this because its very confusing me since the ramp is curved and not straight plane like usual.

Also the circular part is confusing me a lot too.

## The Attempt at a Solution

Do I have to use the conservative energy formula to find the final speed to C ?

I am very sorry I dont have anything as my own work (try) but I really do not know how to do this.

I have never posted a help thread before without any work done.
