Engineering Mechanics - Dynamics Chapter 20 Problem 20-3 The antenna is following the motion of a jet plane. At the instant shown, the constant angular rates of change are θ ' and φ ' . Determine the velocity and acceleration of the signal horn A at this instant. The distance OA is d . Given: 25 deg = ' 0.4 rad s = 75 deg = ' 0.6 rad s = d 0.8 m = Solution: ω ' 0 ' = α 0 '
