A ball that has a mass of 0.25 kg spins in a circle at the end of a 1.6 m rope. The ball moves at a tangential speed of 12.2 m/s.

Verified Answer :

For this case what we must do is calculate the centripetal force of the object.

By definition, the centripetal force is given by:

\(F = m(\frac{v^2}{r})
\)

Where,

v: tangential speed

r: radius of the circular path

m: mass of the object

Substituting values we have:

\(F = 0.25 * (\frac{12.2 ^ 2}{1.6})

F = 23.26
\)

Answer:

The centripetal force of the ball is given by:

\(F = 23.26 N\)

Answer:

The answer is B) 23 N
