A41 g ball rolls around a 64-cm-diameter l-shaped track at 55 rpm. what is the magnitude of the net force that the track exerts on the ball? rolling friction can be neglected.

0.44 N

Explanation:

The net force (centripetal force) acting on the ball is:

where

m = 41 g = 0.041 kg is the mass of the ball

is the angular velocity

is the radius of the track

First we need to convert the angular velocity into rad/s:

And now we can calculate the magnitude of the force:

gets less

i guess it’s a and b
