Answer:
Explanation:
Let
h = height of balloon (in feet).
θ = angle made with line of sight and ground (in radians).
h = 300 tanθ
now can be written as
When θ = π/4,
Explanation:
Using kinematics,
t = 10s
v = 0m/s
a = -9.8m/s^2
Therefore u = v - at = 0 - (-9.8)(10) = 98m/s.
Unless you are a mutant....I don't think you would make it. I'm 5'8" and most people are 6'7" or less. It's bsically impossible to do. :)
