  • Algebra II Math Question?

    A train wheel has a diameter of 30 inches to the rim, which rests on the track. The flange, which keeps the wheel from slipping off the track, projects 1 inch beyond the rim. When the train is traveling 60 mph, what is the linear velocity of a point on the outer edge of the flange?

    Use the formula V = rw, where V is linear velocity, r is radius, and w is angular velocity.

    For starters, what is a flange?
