Question

When it comes to graphs I am no genius lol​

Answer 1

Option B

Step-by-step explanation:

Displacement = Area under the velocity-time graph

So to find the displacement of a particle from 7 to 8 seconds we take the triangle and calculate its area.

`Area\ of\ a\ right\ angled\ triangle = (1)/(2)*(base)*(height) \\\\Area\ of\ a\ right\ angled\ triangle = (1)/(2)*(1)*(3) \\\\Area\ of\ a\ right\ angled\ triangle = 1.5`

So the displacement is 1.5 meters
