Does the ke of a car change more when it accelerates from 23 km/h to 33 km/h or when it accelerates from 33 km/h to 43 km/h?

a. from 23 km/h to 33 km/h
b. from 33 km/h to 43 km/h
c. more information is needed.

b. From 33 km/h to 43 km/h

Explanation:

Lets take mass of the car = m

We know that The change kinetic energy KE is give as

When speed changes from 23 km/h to 33 km/h :

We know that 1 km/h= 0.27 m/s

KE=  20.412m   J

When speed changes from 33 km/h to 43 km/h :

We know that 1 km/h= 0.27 m/s

KE=  27.702m   J

Therefore we can say that when speed changes 33 km/h to 43 km/h ,the kinetic energy will changes more.

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
