1. The problem statement, all variables and given/known data 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; Drawing of the problem: http://i.imgur.com/TrcMJ5I.png 2. Relevant 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. 3. 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.
