REALLY angry...\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "time up = time down , so the ball falls from the peak in 1.25 sec\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "gravitational acceleration (g) is 32 ft/sec^2 ___ that means the velocity increases 32 ft/sec for each second of fall\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "falling for 1.25 sec means the ball is going 40 ft/sec at the bottom (almost 30 mph)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "since the velocity was zero at the peak , the average velocity is (0 + 40)/2 or 20 ft/sec\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "20 ft/sec for 1.25 sec is 25ft ___ two and a half times the height of the rim \n" ); document.write( "
