A ball is whirled overhead at a velocity of 12 meters/second in a circular path whose radius is 2 meters. Select the value listed below that must be substituted for c if the equation for determining centripetal force is defined in this way:

X = B^2*A/C

A. 2

B. 5

C. 6

D. 12

Answer: A. 2

Explanation:

The formula for the centripetal force is given by

[tex]F=m\frac{v^2}{r}[/tex]

where m is the mass of the ball, v is its tangential speed, and r is the radius of the circular path.

The formula written in this problem is:

[tex]X=A\frac{B^2}{C}[/tex]

By comparing the two formulas, we see that

- A corresponds to the mass, m

- B corresponds to the speed, v

- C corresponds to the radius, r

Therefore, since in this problem the radius is 2 meters, then C=2.
