In this problem we have a question with three parts.
00:06
So in the first part we have this object a that moves with uniform motion with velocity equal to 2 .6 meters per second.
00:21
At a certain time this object is at the position given by marked with 13 meters.
00:31
And the question is, what will be the position of this object 25 seconds later? okay, now since we have uniform motion, we are going to get this new position as the initial position at that certain time, plus the velocity times the time difference in between the initial and final positions.
01:05
So if we compute this number, we are going to get 78 meters.
01:12
So this object will be at the position marked with 78 meters, 25 seconds later.
01:23
Next, we have this other object, b, and it is at a position equal to 34 meters.
01:34
And it also travels with uniform motion.
01:38
And the velocity is given to be minus 2 .0 meters per second.
01:45
So it is going in the opposite direction.
01:48
And the question is, what is the new position of this object after 11 seconds? and again, we have this uniform motion.
01:58
So the new position will be the initial position plus the velocity...
