19. (2 points) Given the Rocket class from program 6 which includes instance variables xVel and yvel, write a method called safeLanding () that could be added to the Rocket class and returns true if the rocket made a safe landing and false otherwise. Assume the rocket has landed and you are only deciding if it was a safe landing or not. A safe landing is one in which both the x and y velocities are between -0.4 and 0.4. class Rocket { float xVel, yvel; // most of the class is omitted and not needed for this question // put your safeLanding method here
