Answer: y = v₀tgθx - gx²/2v₀²cos²θ
a = v₀tgθ
b = -g/2v₀²cos²θ
Step-by-step explanation:
x = v₀ₓt
y = v₀y.t - g.t²/2
x = v₀.cosθt → t = x/v₀.cosθ
y = v₀y.t - g.t²/2
v₀y = v₀.senθ
y = v₀senθ.x/v₀cosθ - g/2.(x/v₀cosθ)²
y = v₀.tgθ.x - gx²/2v₀²cos²θ
a = v₀tgθ → constant because v₀ and θ do not change
b = - g/2v₀²cos²θ → constant because v₀, g and θ do not change
Let

be the ellipsoid with equation

so that the volume of

is given by the triple integral

Consider the augmented spherical coordinates given by the identities

Computing the Jacobian, we find that the volume element is given by

so that the volume integral can be written as
Just do 300x1.4 because that gives you the extra 40% (the answer is £420 btws)
Zero point (or decimal) one seven.
Since 1 km = 1000 m then .33 km = 350 m
Hope this helps!
