Question

Which is greater: an acceleration from 40 km/h to 45 km/h, or an acceleration from 100 km/h to 110 km/h, if both occur in the same time interval? Explain your answer. *

Answer 1

Explanation:

A1 = 40km/h

A2 = 45km/h

B1 = 100km/h

B2 = 110km/h

A2-A1 = 45-40 = 5 km/h

B2-B1 = 110-100 = 10km/h..

hence acceleration B is greater
