Textbook Question

Chapter 29, Problem 71GP

CE Predict/Explain Consider two apple pies that are identical in every respect, except that pie 1 is piping hot and pie 2 is at room temperature, (a) If identical forces are applied to the two pies, is the acceleration of pie 1 greater than, less than, or equal to the acceleration of pie 2? (b) Choose the best explanation from among the following:

I. The acceleration of pie 1 is greater because the fact that it is hot means it has the greater energy.
II. The fact that pie 1 is hot means it behaves as if it has more mass than pie 2, and therefore it has a smaller acceleration.

III The pies have the same acceleration regardless of their temperature because they have identical rest masses.

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? Figure P4.46 F= 200 N 4.00 kg 6.00 kg 5.00 kg

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? Figure P4.35 F₁ = 100 N 60° 30° F2 = 140 N

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?
