Problem
A ball is projected vertically upward with initial speed u and experiences a constant resistive force F in addition to gravity mg. During ascent, the downward acceleration is g+mF; during descent, the upward resistive force gives downward acceleration g−mF. For the same vertical displacement upward and downward, determine which interval is longer.
