A weightlifter raises 250 kg from the floor to a height of 2 meters.
a) How much work does he do if:
i) the object is raised straight up
ii) the object is first raised one meter straight up, then sideways 3.5 meters to the
left followed by another meter straight up and finally 3.5 meters to the right
i konw for i we have to use w=mgh, does ii have the same answer as i? if not how do you find it?
thank you
