Algebra.Com's Answer #447310 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! An object is thrown upward from the top of a 96-foot building with an initial velocity of 80 per second. The height h of the object after t is given by the quadratic equation h=16t+80t+96\r \n" ); document.write( "\n" ); document.write( "When will the object hit the ground at when the time is how many seconds? \n" ); document.write( "====================== \n" ); document.write( "Using your equation, it will never hit the ground. \n" ); document.write( "Use h(t) = -16t^2 + 80t + 96 \n" ); document.write( "Notice the first term is negative, and it's t^2. \n" ); document.write( "--------- \n" ); document.write( "Use h(t) = -16t^2 + 80t + 96 \n" ); document.write( "It hits the ground when h(t) = 0 \n" ); document.write( "Use h(t) = -16t^2 + 80t + 96 = 0 \n" ); document.write( "Solve for t \n" ); document.write( "Ignore the negative value of t. \n" ); document.write( " \n" ); document.write( " |
