If a 1500 kg car is moving 20.0 m/s is brought to a stop by brakes. How many kilocalories of heat are generated in the process?

Question

Please include the formula that I should use to find the answer.
-Thanks

Answer 1

Wouldn't the Kinetic energy all turn to heat? KE= 1/2 m v^2

YOu will have to change it to Kcal, as KE is in joules. You can check your calcs by pasting this into Google search window

1/2 * 1500kg * (20m/s)^2 in kilocalories

Answer 2

I tried pasting the equation into google but,nothing happened
