Question

*Best ans BRAINLIEST I promise URGENT*

The variation of velocity of a particle moving along a straight line is shown in the attachment. The distance
travelled by the particle in 4 s is:

(A) 25 m
(B) 30 m
(C) 55 m
(D) 60 m
PROPER EXPLAINATION ALSO NEEDED​

Answer 1

the distance covered will be measured as the area of the shape in the graph

now look carefully you will find a rectangle and a trapezium and a right angled triangle. ( up trapezium down rectangle and a right angled triangle beside it)

area of rectangle:

( l×b)

10×3=30

area of trapezium:

( a+b/2h)

substituting we get 15

area of triangle:

1/2bh

b=1 h=20

substituting we get 10

AND FINALLY...

add them!

30+15+10=55

hope this helps :)
