4.46
The two blocks in Fig. P4.46 are connected
by a heavy uniform rope with a mass of 4.00 kg. An up-
ward force of 200 N is applied as shown. (a) Draw three
free-body diagrams: one for the 6.00 kg block, one for
B
the 4.00 kg rope, and another one for the 5.00 kg block. For each force,
indicate what object exerts that force. (b) What is the acceleration of the
system? (c) What is the tension at the top of the heavy rope? (d) What is
the tension at the midpoint of the rope?

4.35 ⚫ Two adults and a child want to push a wheeled cart in the direc-
tion marked x in Fig. P4.35 (next page). The two adults push with hori-
zontal forces F and F as shown. (a) Find the magnitude and direction of
the smallest force that the child should exert. Ignore the effects of friction.
(b) If the child exerts the minimum force found in part (a), the cart ac-
celerates at 2.0 m/s² in the +x-direction. What is the weight of the cart?

4.21 ⚫ BIO World-class sprinters can accelerate out of the starting
blocks with an acceleration that is nearly horizontal and has magnitude
15 m/s². How much horizontal force must a 55 kg sprinter exert on the
starting blocks to produce this acceleration? Which object exerts the
force that propels the sprinter: the blocks or the sprinter herself?
