Notice that in part (b), unlike part (a), we did not have to multiply by g because we were given the weight (which is a force) and not the mass of the object. (b) Here the force is given as F = 21 lb, so the work done is W = F d = 21 ⋅ 7 = ft − lb. (b) How much work is done in lifting a 21-lb weight 7 ft off the ground? Solution (a) The force exerted is equal and opposite to that exerted by gravity, so the force is F = m d t 2 d 2 s = m g = ( 1.1 ) ( 9.8 ) = N and then the work done is w = F d = ( ) ( 0.7 ) = J.
