Question

1. The displacement time graph of a persde sustom in
the fs is interes from the figure de
Duplecane
r
The
(1) the partide arts with rent velocity but the mo
ton is recording, hence the partide finally store
(2) the velocity of the partide remains content for the
whole time
( 3) the acceleration of the partide remains constant for
the whole time
the partide starts with a constant velody, but the me
ton is acelerated and the velocity of particle is notre
finally.​

Answer 1

Explanation:

Net displacement of the particle in 10 s, S=BC−OA=40−60=−20 m

Total time taken t=10 s

∴ Average velocity of the particle v

avg

=

t

S

=

10

−20

=−2m/s

Thus magnitude of average velocity of the particle is 2m/s.
