a general physics 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?
