A constant upward force of 442n is applied to a stone that weighs 32n. the upward force is applied through a distance of 2.0m, and the stone is then released. to what height, from the point of release, will the stone rise?

The work done on the stone is F•d, where the net force is the applied minus the weight of the stone F=442-32=410N
W=410N•2m=820J.
This will be the maximum gravitational potential energy at its peak assuming no air resistance. GPE is given by E=mgh, where mg is the weight of the stone. Solving for height
h=E/mg = 820/32=25.625m
