v = sqrt (αR)
v = sqrt (2gR)
Determining the time of free fall:
y (t) = y0 + v0yt + (1/2)ayt2
y0 = 2R, v0 = 0 m/s, and ay = -g
Therefore, y = 2R - (1/2)gt2
A ball is launched up a semicircular chute in such a way that at the top of the chute, just before it goes into free-fall, the ball has a centripetal acceleration of magnitude 2g. How far from the bottom of the chute does the ball land?
