The energy, E, released when an object is stopped varies directly as the square of its velocity, v. If an object releases 600kj of energy when stopped from a velocity of 5m/s. How much energy is released when it is stopped from a speed of 12m/s?
\n" ); document.write( "--------------
\n" ); document.write( "E = kv^2
\n" ); document.write( "----
\n" ); document.write( "Solve for \"k\" using \"If an object releases 600kj of energy when stopped from a velocity of 5m/s\".
\n" ); document.write( "-----
\n" ); document.write( "600 = k*5^2
\n" ); document.write( "k = 24
\n" ); document.write( "----
\n" ); document.write( "Equation:
\n" ); document.write( "E = 24*v^2
\n" ); document.write( "-----
\n" ); document.write( "How much energy is released when it is stopped from a speed of 12m/s?
\n" ); document.write( "E = 24*12^2
\n" ); document.write( "E = 3456kj
