A 1.21-g samara- the winged fruit of a maple tree-falls toward the ground with a constant speed of 1.1 m/s (FIGURE 5-38).
(a) What is the force of air resistance exerted on the samara?
(b) If the constant speed of descent is greater than 1.1 m/s, is the force of air resistance greater than, less than, or the same as in part (a)? Explain. |
