A frightened child is restrained by her mother as the child slides down a frictionless playground slide. If the force on the chi
ld from the mother is 116 N up the slide, the child's kinetic energy increases by 30 J as she moves down the slide a distance of 1.9 m. (A) How much work is done on the child by the gravitational force during the 1.9 m descent?
(B) If the child is not restrained by her mother, how much will the child's kinetic energy increase as she comes down the slide that same distance of 1.9 m?
add the two 6 ft together and that gives you 12 ft. then add 7 in + 6 in which gives you 13 in. There are 12 in a foot, so you take 12 away from the 13 giving you 1 in remaining and 1 additional foot to add to the 12.
