Hi, So I have this picture of a ramp with a ball going down. I have figured the average velocity, acceleration, and total distance. Now I have to find out the instantaneous velocity at half the distance? I a not sure how to find the instantaneous velocity, if anyone can help that would be great!

Half way down, the ball has acquired half its maximum kinetic energy, so the velocity is sqrt(1/2) = 70.71% of the final velocity, rather than half the final value.
