FIGURE 4-2
A box weighing 66.0 N rests on a table. A rope tied to the box runs vertically upward over a pulley and a weight is hung from the other end (Fig. 4-37). Determine the force that the table exerts on the box if the weight hanging on the other side of the pulley weighs (a) 30.0 N, (b) 60.0 N, and (c) 90.0 N.
(2) A stack of two crates is being lifted upwards by two cables, as shown in the figure below. The tension
in each cable is 2270 N. You may assume that the masses of the cables are negligible compared to the
masses of the crates. Do not use Newton's 3rd Law; use only Newton's 2nd Law.
(a) Using Newton's 2nd Law, calculate the force that the top crate exerts on the bottom crate and the force
that the bottom crate exerts on the top crate.
(answer: Fotom on-top = Fop on-bottom= 3062 N)
