A ball weighing 0.9N is attached to the lower end of a thin cord of which length is 0.7m. The upper end of the cord is fixed. The ball oscillates along a path of a vertical circle. Determine the tangential component of the acceleration of the ball at the instants when the cord makes the angles of A) 90°, B) 37º, and C) 0° with the vertical direction. Ignore the weight and the friction of the cord.
