Question

A car accelerates from rest to 40 m/s. Later, on a highway it accelerates from 40 m/s to 80 m/s. Which takes more energy, going from 0 to 40, or from 40 to 80

Answer 1

Answer:

40 to 80

Explanation:

A car's kinetic energy changes with the speed.  Cars going slower have less potential energy than cars going faster.
