A diver is standing on a platform 24 ft above the pool. He jumps from the platform with an initial upward velocity of 8 ft/s. How long will it take for him to hit the water.
\n" ); document.write( ".
\n" ); document.write( "general form of equation:
\n" ); document.write( "h(t) = -32t^2 + vt + vo
\n" ); document.write( "where
\n" ); document.write( "h(t) is height at time t
\n" ); document.write( "t is time
\n" ); document.write( "v is initial velocity
\n" ); document.write( "vo is initial height
\n" ); document.write( ".
\n" ); document.write( "h(t) = -32t^2 + 8t + 24
\n" ); document.write( "He hits the water when h(t) is zero:
\n" ); document.write( "0 = -32t^2 + 8t + 24
\n" ); document.write( "0 = 4t^2 - t - 3
\n" ); document.write( "0 = (4t+3)(t-1)
\n" ); document.write( "t = {-3/4, 1}
\n" ); document.write( "we can throw out the negative solution leaving:
\n" ); document.write( "t = 1 second\r
