5. A sprinkler rotates around fixed Point C. The nozzle on Arm A has broken off. So, water exits Arm A in the radial direction, relative to the sprinkler at 2 m/s and the radial velocity of the water is increasing at 0.5 m/s². The sprinkler arms are rotating around Point C at 8 = 6 rad/s, and because the nozzle has broken, it is decelerating with Ö = −1 rad/s². a. At that moment, what are the radial (vr) and theta (ve) components of velocity of the water exiting the sprinkler at Point A? b. Express the velocity vector in rectangular coordinates, in terms of i and j unit vectors. X view from the top 0.1 m 0 = 6 rad /s Ö = -1 rad/s² A w = 2 m/s *w = 0.5 m/s²
