Question

An object with an initial velocity of 27 m/s has a final velocity of 39 m/s after 13 seconds.

What is the object's acceleration?

Answer 1

The answer is 0.92 m/s²

Step-by-step explanation:

To find the acceleration of an object given it's initial and final velocity and time taken we use the formula

`a = (v - u)/(t) \\`

where

v is the final velocity

u is the initial velocity

t is the time taken

a is the acceleration

From the question

v = 39 m/s

u = 27 m/s

t = 13 s

We have

`a = (39 - 27)/(13) = (12)/(13) \\ = 0.923076... \: \: \:`

We have the final answer as

0.92 m/s²

Hope this helps you
