5 seconds is a poor time to ask about, because the speed abruptly changes at exactly 5 seconds.
Up until that time, the speed has been 1 m/s. And then, at exactly 5 seconds, it becomes zero.
_________
It's also a poor question because speed is calculated from the distance covered, but the graph shows displacement, not distance. You can't really tell the distance covered from a displacement graph.
For example, if an object happens to be moving in a circle around the place where it started, then the total distance covered keeps increasing, but its displacement is constant.
Answer:
There are three ways an object can accelerate: a change in velocity, a change in direction, or a change in both velocity and direction.
Explanation:
A booklet is a small book—with fewer pages and smaller dimensions than a “real” book, and usually a paper cover.
I would think 10 but I would have to see the picture
We assume
(acceleration is constant. We apply the equation
where s is the distance to stop
. We find the acceleration from this equation
We know the acceleration, thus we find the distance necesssary to stop when initial speed is
