Algebra.Com's Answer #83704 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! if a gun is fired straight upward, the bullet leave the gun at 100 feet per second, after 2 seconds the velocity of the bullet is 36 feet per second? \n" ); document.write( "there is a linear equation that give the velocity in terms of the time\r \n" ); document.write( "\n" ); document.write( "Find the equation and the velocity after three seconds? \n" ); document.write( "--------------------- \n" ); document.write( "You have two points relating velocity to time: (0,100) and (2,36) \n" ); document.write( "------------ \n" ); document.write( "Slope = (100-36) / (0-2) = -32 \n" ); document.write( "----------------- \n" ); document.write( "Intercept: f(0) = 100 \n" ); document.write( "-------------- \n" ); document.write( "EQUATION: \n" ); document.write( "velocity = -32 t + 100 \n" ); document.write( "================== \n" ); document.write( "v(0)=100 \n" ); document.write( "---------------- \n" ); document.write( "v(3) = -32*3 + 100 = 4 ft. per sec. \n" ); document.write( "=============== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
