Answer:
9600 cm/min
Explanation:
Well, the circumference of the flywheel is 2π×the radius(16 cm). That's how far the spot moves in one revolution.
10 radians per second divided by 2π is the number of revolutions per second.
So multiply that times the circumference and that's the distance the point has traveled.
let the linear speed of the spot be v
therefore, v= 160×60= 9600 cm/min
