An engineering physics student conducted an experiment on free fall motion by launching a toy rocket vertically upward with a speed of 21 m/s from a building 30 m high. The rocket just misses the roof of the building on its way down. How long does it take the rocket (in s) to reach the ground from the launch position? [Express answer in ONE decimal place].
