Question
(Figure 1) A cannonball is fired horizontally from the top of a cliff.
The cannon is at height H = 100 m above ground level, and the
ball is fired with initial horizontal speed v0. Assume acceleration
due to gravity to be g = 9.80 m/s²

Correct answer is shown. Your answer 44.27 m/s was either rounded differently or used a different number of significant figures than required for
this part.
What is the y position of the cannonball when it is at distance D/2 from the hill? If you need to, you can use the trajectory equation for this projectile, which
gives y in terms of a directly:
You should already know vax from the previous part.
Express the position of the cannonball numerically in meters.
