Physics, asked by brijbiharichoubey917, 11 months ago

an EV with the following details. Total mass = 1200 kg, front area = 2 m2, aerodynamic drag coefficient = 0.25 and tire rolling friction coefficient = 0.02, air density = 1.25 kg/m3, acceleration due to gravity = 10 m/s2. Equivalent mass for rotational mass can be taken as 6% of total mass. The wheel is connected to a three phase induction motor with a gear. Gear efficiency is 0.9. Induction motor is operating in constant torque region. The vehicle starts from rest and linearly reaches velocity of 80 km/hr in 10 seconds.
Rolling frictional force is
