A0.015-kg ball is shot from the plunger of a pinball machine. because of a centripetal force of 0.028 n, the ball fol- lows a circular arc whose radius is 0.25 m. what is the speed of the ball?

The speed of the ball is 0.68 m/s

Explanation:

To calculate the speed of the ball, we use the equation used to calculate centripetal force:

where,

F = centripetal force = 0.028 N

v = speed of the ball = ?

m = mass of the ball = 0.015 kg

r = radius of the ball = 0.25 m

Putting values in above equation, we get:

Hence, the speed of the ball is 0.68 m/s
