Question 7
Hy IN, Where µ̟ 1s the coefficient of static friction. For solving problems involving the forces on one or mora objects, it is essential to draw a free-body diagram for each object, showing all the forces acting on only that object. Newton's second law can be applied to the vector components for each object. 7. If you walk along a log floating on a lake, why does the log move in the opposite direction? 8. (a) Why do you push down harder on the pedals of a bicy- cle when first stárting out than when moving at constant speed? (b) Why do you need to pedal at all when cycling at constant speed? 9. A stone hangs by a fine thread from the ceiling, and a section of the same thread dangles from the bottom of the stone (Fig. 4-36). If a person gives a sharp pult on the dangling thread, where is the thread likely to break: below the stone or above it? What if the person gives a slow and steady pall? Explain your answers FIGURE 4-36 Question 9. D. The force of gravity on a 2-kg rock is twice as great as that on a 1-kg rock. Why then doesn't the heavier rock fall faster?
