A 0.3556m long mechanical arm is attached with a ball bearing pivot at one end to a moving body. The entire arm and body assembly are moving at a linear velocity of 6.357 m/s. The body comes to a stop and the arm rotates around it's pivot at a radial velocity of 17.878 rad/s. At the same time, the body reverses, pulling the pivot point back linearly the opposite direction at an linear acceleration of 397.81 m/s2. What is the instantaneous linear velocity of the free swinging end of the arm after 0.0125 Seconds?
