Explanation / Answer

7) time of flight t = d/ v cos theta

= 46/(40 cos 20 degree) = 1.2238 s

Height h = v sin theta *t - 0.5 gt^2

= 40* sin 20 degree *1.2238 - 4.9*1.2238^2

= 9.4 m answer

4b) Distance = pi r = 3.27*pi = 10.273m

2b) north distance = 340 sin 33.5 degree = 187.66m

Angle = arcsin (187.66/518.66)

= 21.21 degree N of W

C) The answer is approximately correct because Earth is not flat which we assumed here.
