    A car of mass 800kg has a maximum speed of 20ms-1 down a slope inclined at 2 degrees to the horizontal. The frictional resistance to motion of the car is constant, and of magnitude 1000N. Take g = 10ms-2.

    a) Find the power of the car’s engine
    b) Find its maximum speed up the same hill.
