# Acceleration Examples

Acceleration is a vector quantity that measures a change in speed or direction. It is defined as a change in velocity per unit of time. Given below is the acceleration examples problems with solution for your reference to calculate acceleration in m / s2.

## Acceleration Example Problems

###### Example 1:

Let us consider the acceleration practice problem: A car accelerates uniformly from 22.5 m/s to 46.1 m/s in 2.47 seconds. Determine the acceleration of the car.

###### Solution:

We can calculate the Acceleration using the given formula.

#### Formula:

Acceleration = ( Final velocity - Initial velocity) / Time

Substituting the values in the formula,

Acceleration = (46.1 – 22.5 ) / 2.47 = 23.6 / 2.47 = 9.554 m/s2

Therefore, the value of Acceleration is 9.554 m/s2.

###### Example 2:

Refer the below example of acceleration with solution. When an airplane accelerates down a runway at 3.20 m/s2 to 5.41 m/s2 for 28 s until is finally lifts off the ground, calculate its acceleration before its take off.

###### Solution:

Substituting the values in the above given formula,

Acceleration = (5.41 – 3.20 ) / 28 = 2.21 / 28 = 0.078 m/s2

Therefore, Acceleration is 0.078 m/s2.
