We are given the rate of rotation of a wheel as well as its radius. In each case, determine the following:

A. the angular speed, in units of radians/sec;

B. the linear speed, in units of cm/sec, of a point on the circumference of the wheel;

C. the linear speed, in cm/sec, of a point halfway between the center of the wheel and the circumference.

1250 rpm; r = 10 cm

I do not get this answer. Moving on....

I will study this further on my own at a near future time. No time to concentrate on math in the current situation.
