Question

A car travelling with a speed of 2 metre per second increases its speed to 10 metre per second in a time interval of 4 second what is the acceleration of car

Answer 1

Answer:

The acceleration of the car is  2$ms^{-2}$

Explanation:

Initial velocity of the car = 2$ms^{-1}$

final velocity of the car = 10$ms^{-1}$

time interval = 4 s

We know that ,

Acceleration = change in velocity / time .

so,        a = ( final velocity - initial velocity) / time interval.

            a = 8/4 $ms^{-2}$

            a =  2$ms^{-2}$

therefore the acceleration of the car is 2$ms^{-2}$.

Hope it helps !

Answer 2

Answer:

acceleration =2m/s² because acceleration means rate of change in velocity/time
