While the swing bridge is closing with a constant rotation of 0.5 rad/s, a man runs along the roadway such that when d = 10 ft he is running outward from the center at 5 ft/s with an acceleration of 2 ft/s2, both measured relative to the roadway. Determine his velocity and acceleration at this instant.
