The equation of the path of a cricket ball thrown at an angle of 45 degrees, with the horizontal is y = x - (x^2)/50 where x metres and y metres are the horizontal distance traveled and vertical height respectively. Calculate the greatest vertical height reached and the total horizontal distance traveled. \n" ); document.write( "------------------- \n" ); document.write( "Max occurs when 1-(2/50)x = 0 \n" ); document.write( "(1/25)x = 1 \n" ); document.write( "x = 25 metres \n" ); document.write( "----- \n" ); document.write( "max height occurs at f(25)= [25 - (25^2)/50]= 25 - (625/50) = 25-12.5 = 12.5 metres \n" ); document.write( "----------------------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "-------\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
