    a general physic q please help!!

    A bob rotates clockwise in a vertical circle at the end of a 1 m long rope. In the pint, where the rope makes the horizontal to the right, the acceleration of the bob is (-2i+3j)m/s^2. At that instant
    -sketch the acceleration vector and find its magnitude,
    -find tangential and radial acceleration,
    -find velocity and speed of the ball
    -is the speed increasing or decreasing in this point?
