Question

s-t graph of a particle in motion in shown in fig . calculate:

a. Total distance covered

b. Total displacement

c. Average Velocity

d. Avg. Speed

• A. 120, 0 ,0 &20
• B. 0,0,0&0
• C. 100,20,40,40
• D. 120,50,20,0

Answer 1

The correct option is A 120, 0 ,0 &20

A) The total distance covered , S

$S=40m+40m+20m+20m=120m$

B) Displacement is the shortest distance between initial and final position,

$Displacement=0m$

C) Average speed,

$Speed=\frac{distance}{time}=\frac{120}{6}=20m/s$

D) Average velocity,

$velocity=\frac{displacement}{time}=\frac{0}{6}=0m/s$
