14. You throw a 2 kg. Stone straight up into the air with a velocity of 6m/s. What is the max height of the stone and the total time it takes for it to come back down?

hf=hi+vi*tat^2 /2
0=0+6t9.8t^2/2
t(64.9t)=0
time of flight: 6/4.9seconds
max height time is onehalf of that.
redo the same equation, knowing time is 1/2 the above t.
