A particle is moving in the xy plane on ...

A particle is moving in the xy plane on a sinusoidal course determined by y = A sin kx, where k and A are constants. The X component of the velocity of the particle is constant and is equal to `v_(0)` and the particle was at origin at time `t = 0`. Find the magnitude of the acceleration of the particle when it is at point having x co ordinate `x = (pi)/(2k)`.
