Question

7. A cannon fires a cannonball with an initial velocity of 300 m/s at 64.0° above the horizontal. The cannonball impacts a raised plateau 43.0 s after firing. Let the +x-direction be directly ahead of the cannon and the +y-direction be upward. Find the x- and y-coordinates of the cannonball's impact point, relative to its firing point (in m).

x= m

y= m
