In 1990 Walter Arfeuille of Belgium lifted a 281.5-kg object through a distance of 17.1 cm using only his teeth.

(a) How much work was done on the object by Arfeuille in this lift, assuming the object was lifted at constant velocity?

(b) What total force was exerted on Arfeuille's teeth during the lift?
