Arocket ship starts from rest and turns on its forward booster rockets, causing it to have a constant acceleration of 4 \,\dfrac{\text m}{{\text s}^2}4 s 2 m ? rightward. after 3\,\text s3s, what will be the velocity of the rocket ship? answer using a coordinate system where rightward is positive.

+12 m/s

Explanation:

The velocity of an object moving of accelerated motion is given by:

where

v0 is the initial velocity of the object

a is the acceleration

t is the time

In this problem, the rocket starts from rest, so . The acceleration is , so the velocity after will be
