What is the power of a fast car?
A 1200 kg car accelerates along a straight horizontal road from an initial speed of 10 kmh
-1
to 60 kmh
-1
in a distance of 100 m. Determine the rate at which kinetic energy is supplied by the engine as the car accelerates.
I understand the question
What is the relevance of the word RATE?
Remind me about kinetic energy
