Question

A car speed increase form 40km per hour to 60km per hour in 5 second calculate the acceleration? ??

Answer 1

First of all convert 40 and 60 km/ h to m/ s
Then find the acceleration by v- u/ t

I hope my answer will help u

Answer 2

a=v-u/t
Initial velocity=40km/hr=40×5/18=11.1m/s
Final velocity=60km/hr=60×5/18=16.6m/s
a=v-u/t
a=16.6-11.1/5
a=1.1/5
a=11/10/5
a=11×5/10
a=5.5m/s^-2
