A man lifts a 13 kg crate directly upwards from the floor to a shelf (6 m high) at constant speed*. (*Neglect the very start and very end of the lift, where the crate would of course need to be accelerated from/to rest.)

a.) What is the work done by the man on the crate?

b.) What is the work done by gravity on the crate?

c.) What is the net work done on the crate?
