If a skateboard rider leaves the ramp at point A with an initial velocity va at a 305° angle and strikes the ground at point B, what are va and the time of flight?
a) va = 0 m/s, time of flight = 0 s
b) va ≠ 0 m/s, time of flight ≠ 0 s
c) va > 0 m/s, time of flight > 0 s
d) va < 0 m/s, time of flight < 0 s
