Answer 2

Answer :-

Acceleration of car - 2.2 m/s

----------------

Given :-

• Speed of car increases from 40 km/hr to 80 km/hr
• Time - 5 second

To Find :-

Acceleration of car.

Solution :-

We know that,

Acceleration = v - u/ t

-----------------

Here,

u - 40 km/hr - 11.1 m/s

v - 80 km/hr - 22.2 m/s

t - 5 sec

-----------------

Acceleration = 22.2 - 11.1 / 5

= 11/5

= 2.2 m/s
