Greetings, I'm new here :).
Straight to my problem. I have a ramp. A ball accelerates down at varying angles, and then it reaches the flat part and travels only in the x-direction. I need to find the velocity of the ball as it moves on this flat part, as it is no longer accelerating.
The Attempt at a Solution
First, I did this: 9.81×sin[itex]\theta[/itex]. This gives me the acceleration of the ball down the ramp at whatever angle.
(9.81×sin[itex]\theta[/itex])cos[itex]\theta[/itex] = x component of acceleration down ramp.
s(length of ramp)=1/2at^2
By the time ball reaches flat part, vx=axt?
Here is an extremely simplistic model of the situation.
