4.17. Set Up: Solve: (a) A 1 kg stone has weight the 1 kg stone is heavier. (b) A 1 slug stone has weight the 1 slug stone is heavier. (c) A 1 slug stone has weight the 1 slug stone is heavier. (d) A 1 kg stone weighs A 1 slug stone weighs The 1 slug stone weighs more. (e) A 1 kg stone weighs The 1 kg stone weighs more. Reflect: kg and slug are units of mass; N and lb are units of force (weight). 4.18. Set Up: Solve: (a) too heavy for a normal adult. (b) this is reasonable. (c) this is reasonable. 4.19. Set Up: The weight of an object depends on its mass and the value of g at its location and is independent of the motion of the object. Solve: (a) 138 N (b) 138 N (c) for both (a) and (b). (d) They would be the same, 138 N. Reflect: The weight of an object is the gravitational force exerted on it by the earth. 4.20. Set Up: The weight of an object depends on its location. The mass of an object is an intrinsic property of the object and doesn’t depend on the location. On earth, Solve: (a)
