a car is running with the velocity of 12 kilometre per hour what will be its velocity after 5 seconds if its acceleration is 2 metre

The velocity after 5 second =19 m/s

Given

Initial velocity =vi = 12 km/h=3.3 m/s

Time=t = 5 s

Acceleration=a = 2 m/s²

Required

Final velocity, vf

Solution

Motion with constant acceleration

Can be formulated :

vf=vi+at

Input the value :

vf=3.3+2.5

vf=9+10

vf=19 m/s
