Question

PLEASE HELP ME!!!
A)FIND THE DISTANCE BETWEEN 10 AND 30.
B)WHAT IS THE NEGATIVE ACCELERATION OF THE BODY.​

Answer 1

Answer:

distance = area under the V-T curve

in this case the rect

area=length×breadth

=20×20(from the graph)

=400 metre

now,acceleration is equal to the slope of the V-T graph

OR

V=U+AT

V=0 ; U=20 ;T=10

O=20+A×10

10A=-20

acceleration = -20/10

= -2m/sec2

hope it helps
