In my lab, I have to calculate the initial velocities of different trials for a ball rolling off a ramp. I had thought that the initial velocity would be zero but my teacher said that that's not it. So I decided to use t=0 and plug it into
x=x0+v0*t+(1/2)*a*t^2 but that gives me an intial velocity of zero too. So yeah, i need help.
Oh yeah, my range for the first trial, the distance the ball traveled, was 75cm.
