    work out the components in the x and y direction of the car's speed at the top of the hill.
    using suvat:
    how long does it take for the car to hit the ground (using only y speed)?
    how far does the car travel along the x in this amount of time (this is the answer to a))?
    b):
    the car's x speed is the same, what's the car's y speed when it hit's the ground?
    Using pythagoras' theorem, what's the total speed at the ground?
