Question

(e) The distance covered by a body after every 3 seconds is given in the table. Time (in s) on 30 6* 9 - 12 Distance covered (in m) min 4X2 8 + 1249 16 Plot the distance-time graph and find the speed of the body.​

Answer 1

Answer:

(a)

The total number of divisions on horizontal axis for 2 s is 5.

The total number of divisions on vertical axis for 2 m/s is 3.

The total displacement of the car during these two seconds will be given as the area under all these squares.

The area under the (3×5) squares is given as:

A

15

​

=2×2 = 4

So, the area under one small square is :

A

1

​

=

15

4

​

Now, the area under the graph for 4 sec is:

the number of squares under the graph is :

n=57 small squares + 6 half small squares

So, total number of squares =60.

So, the distance traveled by the car is the area under the curve.

S=60×

15

4

​

S=16 m
