$\"F\"$ - force you exert
\n" ); document.write( " $\"F%5Bf%5D\"$ - friction force in opposite direction of motion
\n" ); document.write( "Sum the forces.
\n" ); document.write( " $\"F-F%5Bf%5D=ma\"$
\n" ); document.write( " $\"300-mu%2Amg=ma\"$
\n" ); document.write( " $\"300-0.5%2850%29%289.8%29=50a\"$
