never mind people I've been getting myself confused.
Clearly it should just be the velocity of the car divided by the wheel radius and then converted to rpm.
Homework Statement
I have to derive an equation that relates the rpm of an axle that is fixed to a car wheel of radius r, given the velocity of the car
subscripts: w is wheel, a is axle
Homework Equations
angular velocity of the wheel is given by
ω_wheel=2π/T=2πf=v/r_w (1)...
