What is the radius r of the turn if θ = 20.0 ∘ (assuming the car continues in uniform circular motion around the turn)? express your answer in meters?

The answer is 54.18 meters.

Explanation:

Fk = -mg + N cos (20) = 0

Fr = N sin (20)  ( frictional force)

Fr = m (a)         where as a = v²÷r

By putting in the values..

N = mg÷ cos (20)

r = v²÷ g tan (20) (radius equation)

= 13.89²÷ 9.81(tan 20) (gravitational force = 9.81 m/s²)

r = 54.18 meters.

the answer is vanilla

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
