a toy rocket is launched from a 1.4m high platform in such a way that its heigh, h (in meters), after t seconds is given by the equation h= -4.9t+9.1t+1.4. How long will it take for the rocket to hit the ground
\n" ); document.write( "----------
\n" ); document.write( "h= -4.9t+9.1t+1.4
\n" ); document.write( "When it hits the ground, h = 0
\n" ); document.write( "-4.9t+9.1t+1.4 = 0
\n" ); document.write( "Solve for t.
