A 11.161a Robots with telescoping arms are sometimes used to perform tasks (e.g., welding or placing screws) where access may be difficult for other robotic types. During a test run, a robot arm is programmed to extend according to the relationship r =3+0.5cos(4q) and the arm rotates according to the relationship 0 = -t² + nt, where r is in feet, q is in radians, and t is in seconds. Determine the velocity and acceleration of the robot tip A at t = 3 s.
