I have the question:
"Calculate the kinetic energy, $E_k$, when a car of mass $1500$ kg travels at a speed of $108$ km/h."
I converted the $108$ km/h to $108000$ m/h by multiplying by $1000$. I then divided $108000$ by $60$ to get minutes and then again by $60$ to get $30$ m/s I then put these values into the equation for kinetic energy and got $675000$ Joules.
So the final answer I get for this is $675000$ Joules [J] is this correct and if not could you please explain where I went wrong ?
