Question

A ball is thrown vertically upward. Which speed-time graph correctly represents the motion if constant air resistance is not ignored?

G1 Physics · Accepted Answer

With constant air resistance, during ascent retardation is g+f/m, while during descent downward acceleration is g-f/m. Thus speed decreases linearly to zero more steeply during ascent and then increases linearly more slowly during descent. This is Image 3. Hence option C.
