    A lorry of mass 1200 kg climbs a mountain at an angle of sin (theta)=1/20. The mass of the lorry is 16000 kg. the work done by driving force is 1200kj and the resistance to motion is 1240N. The velocity of the lorry at the bottom is 15m/s and at the top is 12m/s. Find the distance from the top to bottom.
