a 0.015 kg ball is hot from the plunger of a pinball machine. Because of the centripetal force of 0.028 N, the ball follows a circular arc whose radius is 0.25m. What is the speed of the ball ?
Added by Chevonne G.
Step 1
Step 1: Write down the formula for centripetal force: \( F_c = \frac{mv^2}{r} \), where \( F_c \) is the centripetal force, m is the mass of the object, v is the speed of the object, and r is the radius of the circular path. Show more…
