(A): On reflection from a rigid boundary (denser medium), there is a complete reversal of transverse wave. (R): Reflection at a denser medium, both the particle velocity and wave velocity are reversed in sign.

Consider a particle moving along the positive direction of X-axis. The velocity of the particle is given by v = alphasqrt(x) ( alpha is a positive constant). At time t = 0, if the particle is located at x = 0, the time dependence of the velocity and the acceleration of the particle are respectively

Give examples for the particle where (a) the velocity is in opposite direction to the acceleration (b)the velocity of the particle is zero but is acceleration is not zero.
