Question

Find the displacement of the body in first 10 seconds in the following graph

Answer 1

15×10=150m as speed and time is given

Answer 2

Answer:

The displacement of the body in first 10 seconds is 150m.

Explanation:

Given the velocity of the body, $v=15m/s$

And the time taken, $t=10s$

The area under the velocity-time graph gives the displacement of the body.

As the graph in the figure is in a rectangular shape, area of rectangle is equal to length times breadth.

Therefore, displacement of the body from the graph,

$s=15\times 10= 150m$

Hence, the displacement of the body in first 10 seconds is 150m.
