Answer:
Part a)
Part b)
Step-by-step explanation:
we have
60 rev/min
Part a) Find the angular speed in radians per minute
we know that
One revolution represent 2π radians (complete circle)
so
To convert rev to rad, multiply by 2π
Part b) Find the linear speed in inches per minute
we know that
The circumference of a circle is equal to
we have
----> given problem
substitute
Remember that
One revolution subtends a length equal to the circumference of the circle
so
To convert rev to in, multiply by 16π
