im confused. how do you relate the RPM from gearbox to a sprocket?

thank you that cleared up alot, but how do you calculate the power and torque needed when the car is at rest to 35 mph?

I am designing a transmission for my class but i have a couple of concepts i kinda confused, i have a 550lbs load, and i want to move 35mph=15.64m/s at a constant speed, assuming the drag coefficient to be Cd=.55 and the coefficient of rolling resistance to be Crr=.3 (tires on sand), i found out...

ok thanks but I am still a little confused when you said Power = Robot velocity * Robot mass * (Coefficient of Rolling resistance * g + acceleration) can we assume a random reasonable velocity and an reasonable acceleration?

I am building a robot with a total mass of 835g, using two servo motors conected to the tires made of rubber which have a 3.33cm radius, and i wanted to know how to find out the total torque required to move the robot taking friction into account, the only things i know are...
