A baseball of mass m is thrown vertically upward from a height r=0 with a speed of 20 meters/sec. The gravitational force on the baseball has a magnitude mg (m = mass, g=9.8 meters/sec2 is the acceleration due to gravity) and is directed downwards. Using Newton's second law, calculate the ball's height as a function of time and from that expression the maximum height of the ball.

2. Relevant equations

F=ma

3. The attempt at a solution

[tex]\sum{F=ma}[/tex][tex]\Rightarrow[/tex]mg=m[tex]\frac{d^{2}x}{dt^2}[/tex][tex]\Rightarrow[/tex]g=[tex]\frac{d^{2}x}{dt^2}[/tex]

That's the least I could think of and I'm not really sure. How exactly would I find the height from the second law?
