Study the v-t graph of a body given below. The displacement of the body
in first 45s is​

Answer 1

Answer:

area of triangle + area of rectangle = displacement

1/2 x 15  x 60 = 450

30 x 60 = 1800

we got 30 like this

45 - 15 = 30

displacement (S) = 450 + 1800

                            =  2,250 m

option c is the answer
