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
8.One of the fastest recorded pitches in major-league baseball,
thrown by Tim Lincecum in 2009, was clocked at 101.0 mi/h. If a
pitch were thrown horizontally with this velocity, how far would
the ball fall vertically by the time it reached home plate, 60.5 ft
away?
