What is the torque requirement on a dc motor to power a toy car?
Specifically, is there an equation that can relate torque (t) required for a dc motor to power a toy car with total weight (c), two wheels each weighing (w) with radius (r), gear friction (g), surface friction (s) between the wheels and the surface, at a velocity (v)?
It should be acceleration (a) and not velocity. Draw a freebody diagram and write one yourself. I'll make comments on your attempt.
