Explanation / Answer

2) se the vertical data to find the time of flight:
y = Yo + Vo*t + ½at²
0 m = 680m + 76.8m/s*sin41º*t - ½ * 9.8m/s² * t²
Dropping units for ease (t is in seconds),
0 = 680 + 50.47t - 4.9t²
This quadratic has roots at t = -7.7 s not possible
and t = 18.0 s

(a) x = Vcos*t = 76.8m/s * cos41º * 18.0s = 1043.3 m

(b) Vy = Vsin + at = 76.8m/s*sin41º - 9.8m/s² * 18.0s = -126 m/s
= arctan(-126 / 76.8cos41º) = -65.3º, or
65.3º below horizontal.
