Question

Find the kenetic energy of a car of mass 700kg racing with a velocity of 10m/s

Answer 1

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
