Answer 1

Answer:

The distance travelled by the particle during the time interval t = 0 to t = 5 s will be 20 meter.

Explanation:

According to the question,

The speed versus time graph is shown in the given figure.

To find out the distance travelled by the particle during the given time interval is :-

We know that,

Distance = Area under speed - time graph

=> ∆S = (1/2) × 5 × 8

=> (1/2) × 5 × 8

=> 1 × 5 × 4

=> 5 × 4

=> 20 meter

$\therefore$ The distance travelled by the particle during the time interval t = 0 to t = 5 s will be 20 meter.
