Problem 3:
In the figure, a solid 0.1 kg ball rolls smoothly from rest (starting at height H-6.1 m) until it leaves the
horizontal section at the end of the track at an angle of 30 degrees above the horizontal, at height / -2.3
m=0.1kg H=6.1m h.2.3m²
(a) Find the velocity of the ball as it leaves the track.
