Question

if a car accelerates from 3 m/s to 12 m/s in 3 seconds,what is the cars average acceleration

Answer 1

12-3/3
9/3
=3 is the ans

Answer 2

The average acceleration is 3m/s²

GIVEN

if a car accelerates from 3 m/s to 12 m/s in 3 seconds.

TO FIND

The average acceleration of the car.

SOLUTION

We can simply solve the above problem as follows;

We know that the average acceleration is defined as the rate of change of velocity with respect to time.

Average acceleration = Change in velocity/Time

Initial velocity = 3m/s

Final velocity = 12m/s

Time taken = 3 seconds.

Average acceleration =

$\frac{12 - 3}{3}$

= 9/3 = 3m/s²

Hence, The average acceleration is 3m/s²
