When a ball is thrown vertically upward, the height s reached varies directly as the square of the speed v with which the ball is thrown.
\n" ); document.write( "A ball thrown with a speed of 40 feet per second reaches a height of 25 feet. Find the EXACT height reached when the ball is thrown with a speed of 60 feet per second.
\n" ); document.write( "---------------
\n" ); document.write( "60/40 = 1.5 times the speed
\n" ); document.write( "1.5^2 = 2.25
\n" ); document.write( "2.25*25 = 56.25 feet
\n" ); document.write( "
