straight line is shown which is in the form of semi-
circle starting from t = 2 to t = 8 s. Select correct statement
(1) Velocity of particle between t = 0 to t = 2 s is positive
(2) Velocity of particle is opposite to acceleration between t = 2 to t=5 S
(3) Velocity of particle is opposite to acceleration between t=5s to t=8s
(4) acceleration of the particle is positive between t1=2s and t2=5s while it is negative between t1=5s to t2=8s​
