    A stone is dropped from a window 5m high what is its speed

    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
