Projectile motion. A ski jumper in an aerial competition leaves thelip of the jump with
a speed of v0 = 36 mph (miles per hour) at an angle of ?0 = 65°above the horizontal. The
landing slope is carefully constructed to conform to the equation y= â 0.020 x2, where x
and y are in meters and the coordinate origin is located at the lipof the jump.
a) What is the skierâs maximum height h above the lip of thejump?
b) At what horizontal range R beyond the lip of the jump does sheland?
c) How long is she in the air?
d) What is her speed when she lands?
