When a car rounds a curve at a certain speed its centripetal acceleration is 3.0m/s^2. What will the acceleration be if it rounds the same curve at twice the speed? (ANS: 12.0m/s^2)
\n" ); document.write( "------------------
\n" ); document.write( "It's 12
\n" ); document.write( "CF = mv^2/r
\n" ); document.write( "It's a function of the square of the speed.
\n" ); document.write( "(2v)^2 = 4v^2 --> 4 times \n" ); document.write( "

\n" );
