It is impossible for a dt-graph to have a vertical line. This would mean that you are at many places at one point in time. It simply can't be done, because we can't teleport lol. You can, however, have a line that is REALLY steep. This would mean that you're travelling really fast. (Covering large amounts of distances in short spans of time) Hope this helped!
Answer:
Explanation:
Given
Ship A velocity is 40 mph and is traveling 35 west of north
Therefore in 2 hours it will travel
thus its position vector after two hours is
similarly B travels with 20 mph and in 2 hours
Thus distance between A and B is
Velocity of A
Velocity of B
Velocity of A w.r.t B
Velocity vs. time graph shows the acceleration as a slope whereas displacement vs. time graph shows the velocity as a slope. So, the given statement is false.
Answer: Option B
<u>Explanation:</u>
To understand the acceleration graphically, consider the x axis of the graph as the run and the y axis as the velocity rise. Now, as we all know that,
We can estimate this through the graph. let's draw the motion of an object with time if it's velocity is changing in every second by 4 m/s. Now if we draw this on graph, we will see that there is a slope between the two corresponding values of time and velocity. This slope defines the acceleration for the object with time.
Now, in the same way, if we draw a distance and time graph respective to the y and x axis; we'll get a slope which defines the velocity of the object i.e. change in distance with time.
Hence, with a velocity vs time graph, we get the slope for acceleration whereas with the distance and time graph, we get the slope for velocity. So both the cases, we see there is no velocity slope on an acceleration and time graph. Hence the statement is false.
20m/s, honestly I have know idea what the asnwer is but if i had to guess, this would be my answer.
