use the general equation of motion with constant acceleration:
\n" ); document.write( "---
\n" ); document.write( "r(t) = r0 + (v0)t + (at^2)/2
\n" ); document.write( "---
\n" ); document.write( "where:
\n" ); document.write( "r(t) = position at time t (meters)
\n" ); document.write( "r0 = position at time 0 (meters)
\n" ); document.write( "v0 = velocity at time 0 (m/s)
\n" ); document.write( "a = constant acceleration (for gravity in the metric system use a = -9.81 m/s^2)
\n" ); document.write( "t = time (seconds)
\n" ); document.write( "---
\n" ); document.write( "r(t) = (-4.905)t^2
