hopefully someone hear can help me.

a man jumps into a swimming pool from a height of 4.7m assuming that his downward acceleration is 9.8 m s

^{2}due to gravity, at what speed does he enter the water.

I really need help knowing what equations to use, i realize i need to work out the time taken and use that to calculate the overall speed but i am having trouble displaying that as i need to show all my workings.

Thanks for your time.
