The motion of the sticker is circular motion with constant speed.
The acceleration of the sticker is centripetal acceleration.
Radius 'r'=0.75 feet
Constant speed 'v' =25 miles per hour=36.67 feet per second
Centripetal acceleration of sticker 'a'=v^2 / r
Centripetal acceleration of sticker 'a'=36.67*36.67 / 0.75
Centripetal acceleration of sticker 'a'=1792.9 feet /s^2
