Question
A ball is thrown straight up into the air with a velocity of 12 m/s. Draw a motion diagram for the ball and then give as much quantities information as you can about the motion.
I know you guys can draw anything on this platform. But can you lead me to answer by giving directions.
Thanks!

The acceleration is constant, which means the ball is slowing down with time at a constant rate.
velocity-time graph
velocity starts at some V, then decreases linearly to zero (at the top), and continues down on the same line as it descends.
it ends at v=-12m/s.
position time: starts at zero, increases on a parabola (h=vi*t-1/2 g t^2) until the top (when velocity is zero), then decreases on the other side of the parabola until hf=0 at v=-12
