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

$KE=\dfrac{1}{2}m(v^2-u^2)$

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

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

$KE=\dfrac{1}{2}m(v^2-u^2)$

$KE=\dfrac{1}{2}\times m((0.27\times 33)^2-(0.27\times 23)^2)$

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

$KE=\dfrac{1}{2}m(v^2-u^2)$

$KE=\dfrac{1}{2}\times m((0.27\times 43)^2-(0.27\times 33)^2)$

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.
