A stone is dropped off the edge of a cliff. The height (h metres) of the cliff is proportional to the square of the time (t seconds) taken by the stone to reach the ground.
Write down a relationship between h and t, using k as the constant of variation.

A stone is dropped off the edge of a cliff. The height (h metres) of the cliff is proportional to the square of the time (t seconds) taken by the stone to reach the ground. Calculate the value of k, using the information, "The stone takes 5 seconds to reach the ground when dropped off a cliff, 125 m high.'
