Four speed$-$time graphs are shown below
Which graph represents the following case ?
$(i)$ A ball thrown vertically upwards and returning to the hand of the thrower ?
$(ii)$ A body decelerating to a constant speed and then accelerating.
$(i)$ Graph $(a)$ represents this case. The ball starts with initial velocity; experiences retardation and its velocity decreases to become zero at the highest point. Thereafter the ball falls down and its velocity increases till it again becomes equal to the initial velocity of throw.
$(ii)$ Graph $(d)$ shows the case of a body decelerating to a constant speed and then accelerating.
