solution of A truck loaded with cannonball watermelons stops suddenly

to avoid running over the edge of a washed-out
bridge (Fig. P4.62). The quick stop causes a number of
melons to fly off the truck. One melon rolls over the
edge with an initial speed vi � 10.0 m/s in the horizontal
direction. A cross-section of the bank has the shape
of the bottom half of a parabola with its vertex at the
edge of the road, and with the equation
where x and y are measured in meters. What are the x
and y coordinates of the melon when it splatters on the
bank?
y2 � 16x
