Current Attempt in Progress
Your answer is partially correct.
In the figure, a 0.26 kg block of cheese lies on the floor of a 890 kg elevator cab that is being pulled upward by a cable through distance
d₁²
= 2.6 m and then through distance d₂ = 10.7 m. (a) Through d₁, if the normal force on the block from the floor has constant
magnitude FN = 3.73 N, how much work is done on the cab by the force from the cable? (b) Through d2, if the work done on the cab by
the (constant) force from the cable is 93.96 kJ, what is the magnitude of FN?
