A rocket is fired in te air from the top of a building that is 200 feet tall. the initial velocity of the rocket is 600 feet per second.
\n" ); document.write( ".
\n" ); document.write( "a. write the height function
\n" ); document.write( "h(t) = -32t^2 + 600t + 200
\n" ); document.write( ".
\n" ); document.write( "b. When does the rocket reach it maximum height
\n" ); document.write( "at the vertex:
\n" ); document.write( "t = -b/(2a)
\n" ); document.write( "t = -600/(2(-32))
\n" ); document.write( "t = -600/(-64)
\n" ); document.write( "t = 9.375 seconds
\n" ); document.write( ".
\n" ); document.write( "c. What is the rocket's maximum height d. when does it hit the ground?
\n" ); document.write( "plug answer from b. into the equation:
\n" ); document.write( "h(t) = -32t^2 + 600t + 200
\n" ); document.write( "h(9.375) = -32(9.375)^2 + 600(9.375) + 200
\n" ); document.write( "h(9.375) = 3012.5 feet
\n" ); document.write( " \n" ); document.write( "
\n" );
