Does the KE of a car change more when it
accelerates from 27 km/h to 37 km/h or when
it accelerates from 37 km/h to 47 km/h?
1. More information is needed.
2. No diﬀerence
3. From 37 km/h to 47 km/h
4. From 27 km/h to 37 km/h

Have you tried squaring the numbers? (Velocity is squared in the KE formula)
Compare (47)^2  (37)^2 with
(37)^2  (27)^2
Which is greater?
