(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] Conservation of EnErGy Problem help please :(

1. The problem statement, all variables and given/known data

If a Saturn V rocket with an Apollo spacecraft attached has a combined mass of 2.3 105 kg and reached a speed of 11.2 km/s,how much kinetic energy would it then have?

2. Relevant equations

k= m(vsquared)/ 2

3. The attempt at a solution

I multiplied 11.2km by 1000m to get 112000m and i squared that. then i multiplied it by 105kg and then divided by two but i got the wrong answer. please help! what am i doing wrong! thank you soo much.
