A 1.5-kg collar is attached to a spring and slides without friction along a circular rod in a vertical plane. Knowing that the tension in die spring is 70 N and the speed of the collar is 3.8 m/s as it passes through point A, determine, at that instant, the radial and transverse components of acceleration of the collar.
