Below are 3 views of the cliff on a hill called Roseberry Topping near Middlesbrough. You need to calculate the speed at which a rock would hit the ground if it was dropped over the edge of the cliff. You can use ideas of potential and kinetic energy, or use the equations of uniformly accelerated motion, depending on what you have been taught. You will have to estimate at least one of the numbers - say how you guessed how big it was from the photographs.
