What is the velocity of the object at 4 s 083 ms 087 ms 33

What is the velocity of the object at 4 s ? 0.83 m/s 0.87 m/s 3.3 m/s 5.0 m/s 24 m/s

As the quantity along the Y axis is out of display, I will solve the given problem assuming it to be the displacement.

We know that for x vs time graph, the slope of the line gives the velocity of the body under consideration.

Now for the given graph, the slope remains constant throughout, hence the velocity remains constant.

The distance at t=0 is 5 m and that at t = 3 seconds is 15 m

Hence the slope is given as V = 15 - 5 / 3 = 10/3 = 3.3 m/s

Now as the slope remains the same throughout, the velocity will be same for t = 4 seconds and be equal to 3.3 m/s
