Graph a velocity-time line (solid) and the acceleration-time line (dashed) of a ball being rolled up an incline by a push of a person's hand, changing direction and rolled back down and stopped by the catch of the person's hand.

Velocity time graph should be downward sloping, taking positive going up the slope

$\displaystyle v=u+at$
$\displaystyle v=u-(gsin\theta) t$
The acceleration time graph should constant which equals $\displaystyle -gsin\theta$ at any time if the push provided by the hand is ignored.
