Algebra.Com's Answer #2028 by Earlsdon(6294)![]() ![]() ![]() You can put this solution on YOUR website! The quadratic equation to which you refer but failed to include is:\r \n" ); document.write( "\n" ); document.write( "h(t) = -16t^2 + (vo)t + ho \n" ); document.write( "Where: t is time in seconds, vo is the initial upward velocity of the object, and ho is the initial height of the object.\r \n" ); document.write( "\n" ); document.write( "In this problem, the object is a baseball, which does not alter the mechanics of the situation. \n" ); document.write( " The initial upward velocity has been omitted, and the initial height of the baseball is that of the thrower or 200 ft.\r \n" ); document.write( "\n" ); document.write( "The upshot (no pun intended) is that unless and until you provide the quadratic equation to which you allude or the initial upward velocity with which the baseball was propelled, a solution cannot be found. \n" ); document.write( " |
