Algebra.Com's Answer #61516 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! Suppose a baseball is shot up from the ground straight up with an initial velocity of 32 feet per second. A function can be created by expressing distance above the ground, s, as a function of time, t. This function is s = -16t2 + v0t + s0 \n" ); document.write( "• 16 represents ½g, the gravitational pull due to gravity (measured in feet per second 2). \n" ); document.write( "• v0 is the initial velocity (how hard do you throw the object, measured in feet per second). \n" ); document.write( "• s0 is the initial distance above ground (in feet). If you are standing on the ground, then s0 = 0. \n" ); document.write( "--------------------- \n" ); document.write( "s(t) = -16t^2+32t+0 \n" ); document.write( "------------------------ \n" ); document.write( "How long will it take to hit the ground? \n" ); document.write( "When it hits the ground s(t)=0 \n" ); document.write( "solve for \"t\": \n" ); document.write( "-16t^2+32t=0 \n" ); document.write( "-16t(t-2) = 0 \n" ); document.write( "t = 0 or t=2 \n" ); document.write( "It will start at the ground and be back on the ground after 2 seconds. \n" ); document.write( "==================== \n" ); document.write( "Cheers \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
