Question

24. Figure shows the velocity - time graph of a body moving in a straight line. Find
i) Distance travelled by the body in 20s.
ii) The displacement of the body in 20s.
iii) The average velocity in the time interval t=0 to t=20s.
a) 20m,0,0
b) 0,10m,0 c) 60m, 0,0 d) 0,0, 20ms-1 ​

Answer 1

Answer:

c

Explanation:

i) looks distance cannot be negative

so the total distance equal to sum of the area of the two tringle

ii)Displacement can negative or positive so when we add the both tringle they cancle each other bcoz the upper tringle area is positive but the lower tringle is negative

so total displacement is 0

iii) As the total displacement 0 so total avg velocity will also 0
