Question

Position
-
time
graph
of
a
particle
moving
along
straight
line
is
shown
which
is
in
the
form
of
semi
-
circle
starting
from
t
=
2
s
to
t
=
8
s
.
Select
(
2
)
Velocity
of
particle
is
opposite
to
acceleration
6
the correct statement.
x(m)
t(s)
(0,0) 2
5
8
(1) Velocity of particle between t = 0 to t = 2 s is
positive
between t = 2 to t = 5 S
(3) Velocity of particle is opposite to acceleration
between t = 5 to t = 8 s
(4) Acceleration of particle is positive between
ty = 2 s to tz = 5 s while it is negative
between ty = 5 s to tz = 8 s
