Problem 40E

You throw a baseball straight upward. The drag force is proportional to v2. In terms of g, what is the y-component of the ball’s acceleration when the ball’s speed is half its terminal speed and (a) it is moving up? (b) It is moving back down?

Step-by-Step Solution:

Solution 40E Step 1 of 5: 2 The drag force, f = Dv Weight, W= mg Where m is the mass of the ball and g is acceleration due to gravity. Using newton’s law, Force along vertical direction(y-component), F= ma=Dv ± mg ……………..1 Depending on whether the ball is moving up or down.
