Question

From the velocity-time plots hown in figure,find the distance travelled by the particle during the first 40 seconds.Also find the average velocity during this period.

Answer 1

The distance fravelled by the particle during the first 20 second.

The distance travelled by the partile during next 20 second is

Since distance is a sclar quantity therefore

total distance = S₁ + S₂ = 50 + 50
