Algebra.Com's Answer #376580 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! a rocket is launched from an 18-foot cliff with an initial velocity of 80 feet per second. the height above the ground of the rocket t seconds after launch is given by the equation h= -16^2+80t+18. hjow long after the rocket is launched will it hit the ground? round your answer to the nearest tenth. \n" ); document.write( "------------- \n" ); document.write( "It's when h = 0. \n" ); document.write( "h= -16^2+80t+18 = 0 \n" ); document.write( "Solve for t. \n" ); document.write( "--------------- \n" ); document.write( "Why is this called a rocket? It has no engine, doesn't accelerate. \n" ); document.write( " |
