Dacia wants to know how to determine the polar coordinate θ. What should Katarina tell Dacia?
crimeas [40]

Answer:

r = √ x² + y²   and θ = tan⁻¹ y / x

Explanation:

The polar coordinates are obtained by transforming the Cartesian coordinates (x y) into others (r tés), for this we use to find r the Pythagorean theorem

          r = √ x² + y²

To find teas we use trigonometries

       tan θ = y / x

      θ = tan⁻¹ y / x

In general the angle can be given in any unit, but the most used in physics is in radians

IrinaVladis [17]

Answer:

176.58 m

Explanation:

t = Time taken = 6 seconds

u = Initial velocity = 0

v = Final velocity

s = Displacement

g = Acceleration due to gravity = 9.81 m/s² = a

Equation of motion

s=ut+\dfrac{1}{2}at^2\\\Rightarrow s=0\times t+\dfrac{1}{2}\times 9.81\times 6^2\\\Rightarrow s=176.58\ m

The object travels 176.58 m from the cliff in 6 seconds.
