Step-by-step explanation:
since the equation is v = 1.225 × sqrt(a)
we can plug in the known values to find the altitude.
so:
(67.1/1.225)^2 = a
a = 3000
Base on the visibility formula v = 1.225√a, the altitude at which Dereck is hang gliding is 7.4 miles
The visibility formula is given as follows:
v = 1.225√a
where
Therefore,
v = 67.1 miles
67.1 = 1.225√a
divide both sides by 1.225
√a = 67.1 / 1.225
√a = 54.7755102041
square both sides
√a² = √54.7755102041
a = 7.40104789878
a = 7.4 miles
