A car of mass 2000 kg is moving at a speed of 20 m/s up an inclined plane making an angle 30° with the horizontal. At some point, the motor stops, and the car continues to move along the plane due to its initial velocity. If it is just able to reach the destination which is at a height of 10 m above the point, calculate the work done against friction acting between the tyres of the car and the plane. (Assume g = 10 m/s2 )
