Question: A scooter is designed to roll down a 3 percent slope at a constant speed. Assuming that the coefficient of kinetic friction between the 25-mm-diameter

A scooter is designed to roll down a 3 percent slope at a constant speed. Assuming that the coefficient of kinetic friction between the 25-mm-diameter axles and the bearing is 0.12, determine the required diameter of the wheels. Neglect the rolling resistance between the wheels and the ground.
