Question

An object is moving east, and its velocity changes from 65 m/s to 25 m/s in 10 seconds. Which describes the acceleration? negative acceleration of 4 m/s2 positive acceleration of 4 m/s2 positive acceleration of 9 m/s2 negative acceleration of 9 m/s2

Answer 1

Answer: negative acceleration of 4 m/s^2

Explanation: i took the exam on edge

Answer 2

The one that most likely recounts acceleration in the given scenario would be:

A). Negative acceleration of 4 m/s^2

Given that,

The direction of the object = East

Change in Velocity = Final velocity - Initial Velocity

$= 25 - 65 m/s$

$= -40 m/s$

As we know,

Acceleration $=$ Change in Velocity ÷ time

$= -40$ ÷ $10$

$= -4$ $m/s$

Thus, option A is the correct answer.
