A soccer player kicks a ball straight up into the air at 6m.s per second.Ignore air friction.
1.What is the height of the ball at its highest point
2.What ie the ball's acceleration at its highest point
3.Calculate the maximum height reached by the ball

1. Henry

1. V^2 = Vo^2 + 2g*h
h = (V^2-Vo)/2g = (0-6^2)/-19.6=1.84 m.

2. Zero.

3. Calculated in #1.
