Position time graph of a particle moving along straight line is shown which is in the form of semicircle starting from t = 2 to t = 8 s. Select correct statement

Options

A. Velocity of particle between t = 0 to t = 2 s is positive
B. Velocity of particle is opposite to acceleration between t = 2 to t = 5 s
C. Velocity of particle is opposite to acceleration between t = 5 to t = 8 s
D. Acceleration of particle is positive between `t_(1)=2s" to "t_(2)=5s` while it is negative between `t_(1)=5s" to "t_(2)=8s`

Answer

B
