Example on Average Acceleration Formula

Example 1: Kabir bought a new car which can get off 0 to 60 m/s in 7 seconds only. Estimate the average acceleration of the car.

Solution:

Given:

• Final Velocity v_f = 60 m/s
• Initial Velocity v_i = 0
• Time(Δt) = 7 sec

A_avg = Δv/Δt

A_avg = 60/7

A_avg = 12.86 m/s²

Therefore, the acceleration of the car is 12.86 m/s².

Example 2: A bus driver is driving on a narrow path at 14 m/s and is about to hit a pup that is running across the street. Therefore, the bus gradually started slowing down from the speed of 3 m/s while taking 1.5 sec to do so. Calculate the bus acceleration.

Solution:

Given:

• v_f = 3 m/s
• v_i = 45 m/s

A_avg = Δv / Δt

A_avg = (3 – 45) / 1.5

A_avg = (- 42) / 1.5

A_avg = – 28 m/s²

Acceleration of the bus is -28 m/s². Here, negative sign signifies speeding up of the object.

Average acceleration formula is the change in the velocity divided by the time interval. And the formula for the same is, the average acceleration formula = (change in velocity)/(time taken). Acceleration or average acceleration is measured in m/s².
