Is stone take longer for the downward motion than for the upward motion
Consider a stone thrown vertically upward. if we take friction against air into account, we see that the mechanical energy(1/2mv^2+ mgy) must decrease as a function of time. From this prove that the stone will take longer for the downward motion than for the upward motion
