Calculate the force a mother must exert to hold her 12.0 kg child in an elevator under the following conditions.
(a) The elevator accelerates upward at 0.850 m/s2.
NCalculate the ratio of this force to the weight of the child.
(b) The elevator moves upward at a constant speed.
N
Calculate the ratio of this force to the weight of the child.
(c) The upward bound elevator decelerates at 2.30 m/s2.
(d) Show the free body diagram used (same for all parts). Do this on paper. Your instructor may ask you to turn in this work.
