Explanation / Answer

At the peak of its trajectory after being thrown straight up: The object's velocity is zero and suffered fromgravitational acceleration, so it will change direction and thenspeed up An object falling straight down at a speedhigher than its terminal speed Definitely it will slow down to the terminalspeed An object falling straight down at its terminalspeed At the terminal speed, its weight equal to theair resistance, hence no acceleration An object fallingstraight down at a speed lower than its terminal speed Then it will speed up to the terminalspeed
