Question

An object with an initial velocity of 53 m/s has a final velocity of 77 m/s after 78 seconds. What is the object's acceleration?

Answer 1

Given:

The initial velocity of the object is

`v_i\text{ = 53 m/s}`

The final velocity of the object is

`v_f=\text{ 77 m/s}`

The time taken by the object is t = 78 s

To find the object's acceleration.

Step-by-step explanation:

The object's acceleration can be calculated as

`\begin{gathered} a=(v_f-v_i)/(t) \\ =(77-53)/(78) \\ =0.308\text{ m/s}^2 \end{gathered}`

The acceleration of the object is 0.308 m/s^2
