ANSWER:
Step 1 of 4
a.)
We have to find the angular speed of the ball when it is on the frictionless side of the track.
The angular speed of the ball can be found using the expression,
where,
linear speed in m/s
radius of the ball in m
Now, the linear speed can be determined by applying conservation of mechanical energy to the system.
That is (constant)
