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. (a) What is the force of air resistance exerted on the samara? (b) If the constant speed of decent 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.
