Am studying for a upcoming test and am a little lost on the whole gravity and acceloration thing.
The question am working on is like this
"I ball is thrown stright up with a speed 25m/s"
The first part of this question is how high does the ball go.
I figured that to be 31.98m
25/9.81 = 2.55 The ball will reach 0 speed after 2.55s
then i divided 25/2 and got 12.5m/s
then 2.55*12.5 = 31.89m
now the hard part, I need to know what the times are when the ball reaches half the heigth.
am not really good at using all the formulas, could somone please explane the process very basicaly to me?
