Question

The velocity of a car increases from 10.0 m/s to 11.5m/s in 3.00s.what is the acceleration of the car?

Answer 1

Answer:

Acceleration of the car is 0.5 $m/s^2$

Explanation:

Initial velocity u= 10 m/s

Final velocity v =11.5 m/s

time taken t= 3 s

Acceleration ?

From the equation of the motion , we have

$v=u+at\\11.5=10+a\times 3\\3a=11.5-10\\3a=1.5\\a=0.5 m/s^2$

Acceleration of the car is 0.5 $m/s^2$
