A particle starts from rest at O and moves along a horizontal semi circular track OAB of radius R Im as shown in the figure The rate of change of speed of the particle is constant and equals to 2m s A is a point lying exactly on the middle of semicircular track as shown in figure When the particle reaches A Find a The magnitude of velocity vector of the particle at the instant b Magnitude of acceleration vector of the particle at the instant c The cosine of angle between acceleration and velocity vector of the particle at that instant ke A X
