at highway speeds, a particular automobile is capable of an acceleration of about 2.6 m/s^2. at this rate, how long does it take to accelerate from 60 km/h to 110 km/h?
we know that accelaration = change in velocity/time
here change in velocity = 110 - 60 = 50km/h
converting it into m/s = 13.89m/s..
so time required to increase the velocity = 13.89/2.6
which is 5.34seconds..
