Answer:

35000 KJ

Step-by-step explanation:

The equation for the kinetic energy is given by the formula :


E_(k) = (1)/(2) mv^(2)


E_(k) = (1)/(2) (700)(10)^(2)


E_(k) = (1)/(2) (700)(100)


E_(k) = (350)(100) OR
E_(k) = (1)/(2) (70000)


E_(k) = 35000

Units will be kilojoules since the units of mass was kilograms .

Our final answer is 35000 KJ

Hope this helped and have a good day
