Question

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

Answer 1

Answer:

The answer is 0.92 m/s²

Explanation:

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

$a = \frac{v - u}{t}$

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

$a = \frac{39 - 27}{13} = \frac{12}{13} \\ = 0.923076... \: \: \:$

We have the final answer as

0.92 m/s²

Hope this helps you
