What is the y position  0 pts pending A cannonball is fired
horizontally from the top of a cliff.The cannon is at height H =
70.0 m above ground level, and the ball is fired with
initialhorizontal speed v_0. Assume acceleration due to gravity
to be g = 9.80 m/s. What is the y position of thecannonball when
it is at distance D/2 from the hill? If you need to, you can use
thetrajectory equation for this projectile, which gives y in
terms of xdirectly:  y = H - \frac{g x^2}{2 v_{0\rm x}^2}.  You
should already know v_0x from the previous part. Express the
position of thecannonball numerically in meters. vox is 52.9
y_D/2 =?  Answers (2)    • Anonymous       View this solution...
