a vehicle is accelerating on a straight road its velocity at any instant is 30 km/h, at 2 second it is 33.6 k/h and after further 2 sec it is 37.2 km/hr find the acceleration of the vehicle in meter per second square. Is the acceleration uniform. |

Answer» At t=0 v=30*(5/18)m/s v=8.33 m/s t=2 v1=33.6*(5/18) m/s v1=9.33 m/s t=4 v2=37.2*(5/18) v2=10.33 m/s Since the velocity is INCREASING 1m/s every 2 sec THEREFORE it is a uniform acceleration of 0.5 m/s^2 Please MARK as brainliest !! |
