Hypothetically a pebble rolls off the roof edge of Golden Eagle Arena and falls vertically. Just before it reaches the ground, the pebble's speed is 17 m/s. Neglect air resistance and determine the height of Golden Eagle Arena's roof edge.

17/9.8=1.73s
x=vt1/2at^2
y=(17)(1.73)1/2(9.8)(1.73)^2=14.7m
