Expert Answer

Step 1

A wheel is rotating at 4 radians per second and the diameter of the wheel is 57 -  inches.

Here, 1 radian = Circumference / 2π.

1 radian -= d / 2.

Substitute 57 inch for d in 1 radian,

1 radian -= 57 inches / 2

1 radian = 28.5 inches.

 

Step 2

Obtain the speed of a point o...
