A camera on the ground is 10 km away from a launch pad. From there it tracks a rocket launched vertically into the atmosphere. At a certain instant, the angle of elevation from the camera to the rocket is 21/3 radians and is changing at a rate of 0.5 radians per second. Determine the rocket's velocity at that instant.
