Short Project on Forces acting on a vehicle

Objective: 1. What should be the maximum speed of the motor used in an electric scooter capable to run at 90 kmph, if the fixed gear ratio is 7 and tire size is 90/100 R10 53J? How to read a tire? Recalculate the same value if the tire code is 90/90 R18 51P? We know, `omega = G * V/r` G=7 `= 90 kmph` `V = 90*1000/3600`…
