To solve this problem we will apply the concepts related to the equations of linear motion and angular motion in order to find the radius. Our values are given as,

g=9.81m/s^2

Then

4g= 39.24 m/s^2

The relation between the acceleration and the angular velocity and the radius is,

a_c=\omega^2*r

The angular velocity and the lineal velocity can be related as,

v=\omega r

The acceleration and the velocity was given, then

39.24=\omega^2 r

600=\omega r \rightarrow r = \frac{600}{\omega}

Replacing at the first equation we have,

39.24 = \omega^2 (\frac{600}{\omega} )

\omega = \frac{39.24}{600}

\omega = 0.0654rad/s

Now using this expression to find the radius we have that

r = \frac{600}{\omega}

r = \frac{600}{0.0654}

r = 9174.31 \approx 9200m

Therefore the correct answer is C.

Answer:

16.6 N

Explanation:

m = 0.52 kg, v₀ = 0, v = 8.6 m/s, t = 0.27 s

a = (v - v₀)/t

F = ma = m(v - v₀)/t = 0.52 (8.6 - 0)/0.27 = 16.6 N
