The collar P slides outward at a constant relative speed u along rod AB, which rotates counterclockwise with a constant angular velocity of 24 rpm. Knowing that r = 250 mm when θ = 0 and that the collar reaches B when θ = 90°, determine the magnitude of the acceleration of the collar P just as it reaches B.

(75°f − 32) × 5/9 = 23.889°c

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

it has to be b, about 97 percent.
