A partiv=cle along a plane cirve from point A to a point B. The path length between A and B is 60 in. The speed at A is 80 in/s and at B is 40 in/s. The rate of change of the speed is constant. a) find the tangential component of the acceleration when the particle is at B. b) if the magnitude of the acceleration at B is 60 in/s^2, find the radius of the curvature of the path B.
