amny thanks i appreciate your help

at 5m it has gravitaitional potential energy and when its is dropped it is converted to kinetic energy ive got the formula for GPE it is height x weight and for kinetic energy its 1/2 x mass x speed^2 these might not be the right formulas as i don't have the mass

Ok this might be a simple problem but i have no idea how to do it; A stone is dropped from a window 5m high what is its speed when it hits the ground. I don't need answer i just need a formula or some guidence Thanks
