A car of mass 1220 kg travels up a striaght road which is inclined at an angle to the horizontal, where sin = 0.05. the resistance to motion are modelled as a constant force of magnitude 1400N. The car travels a distance 25.8 metres whilst increasing its speed from 8m/s to 12m/s. Calculate the work done by the car's engine.
I'm new to work done and don't really understand it yet? Thanks

Draw a nice diagram first, then consider energy changes.
