Chap4-HW1 Questions 7. An airplane flying horizontally at a constant speed of 350 km/h over level ground releases a bundle of food supplies. Ignore the effect of the air on the bundle. What are the bundle\'s initial (a) vertical and (b) horizontal com

Chap.5 HW2 Questions 5. Free-body diagrams are shown for four situations in which an object is pulled by several forces across a frictionless floor, as seen from overhead. In which situations does the object\'s acceleration have (a) an x component and

Chap. 2 HW part 2 Question 4. The following equations give the velocity v(t) of a particle in four situations: (a) v = 3; (b) v = 4t2 + 2t - 6; (c) v = 3t - 4; (d) v = 5t2 - 3. To which of these situations do the equations of Table 2-1 apply? The eq

Chap.3 HW Questions v v 3. Equation 3-2 shows that the addition of two vectors a and b is commutative. Does that v v v v mean subtraction is commutative, so that a - b = b - a ? v v v v v v a - b = - - a + b = - b - a . Answer: NO ( ) ( ) 7. Whic

Chap. 2 HW part 1 Questions 2. Figure 2-15 is a graph of a particle\'s position along an x axis versus time. (a) At time t = 0, what is the sign of the particle\'s position? At t = 0, x is negative Is the particle\'s velocity positive, negative, or 0 a

Chap.6 HW1 Questions v horizontal fS 1. In three experiments, three different horizontal force F forces are applied to the same block lying on the same countertop. The force magnitudes are F1 = 12 N, F2 = 8 N, and F3 = 4 N. In each experiment, the bl

Chap. 7. HW Questions 4. Figure 7-18a shows two horizontal forces that act on a block that is sliding to the right across a frictionless floor. Figure 7-18b shows three plots of the block\'s kinetic energy K versus time t. Which of the plots best cor

Chap.5 HW1 Questions 4. At time t = 0, a single force F of constant magnitude begins to act on a rock moving through deep space in the positive direction of an x axis. The rock continues to move along that axis. (a) For time t > 0, which are possible

Chap.6 HW2 Questions 9. In Figure 6-17, a horizontal force of 100 N is to be applied to a 10 kg slab that is initially stationary on a frictionless floor, to accelerate the slab. A 10 kg block lies on top of the slab; the coefficient of friction bet
