A 70 kg student stands on top of a 5.0 m platform diving board . how much gravitational potential energy does the student have? how much work did it take for the student to travel from the ground to the top of the platform diving board?

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.
