Well.. consider total time as t.. then you can divide the sum into two parts fall during first t1 seconds.. and fall during next 1 second since you know what is the height of cliff.. and what is the distance travelled in last second.. you can find out what is the distance travelled in first t1 seconds.. now use equation of motion and get an equation in t and u now using this data.. use the equation of motion for the second part.. the last second
