We can see only 180 degrees ahead.. but any view which is behind that is impossible to see because of that....
I think it’s 5.0 X 10 8Hz
vf=vi+at
No need for rearranging because it is already set up for Vf (final velocity)
a= -9.8m/s² (because it is falling)
vi= 0
t= 2.7
0 + -9.8(2.7) = vf
vf = -26.5 (-26.46)
Answer:
V = 308.06 miles/hour
θ = 13.13° west of north.
Explanation:
Airplane speed = V₁ = 300 miles/hour
Wind speed = V₂ = 70 miles/hour
Resultant speed of the plane = V = ?
As airplane is trying to fly straight North and wind is blowing toward the west. So the angle between airplane velocity and wind velocity is 90°.
By Pythagoras Theorem
V =
V = 
V = 308.06 miles/hour
θ = tan⁻¹(70/300)
θ = 13.13° west of north.
