Consider two astronauts, floating in space, playing catch where they are not in any neighbouring gravitational fields. Describe what would happen to the astronauts as they continue to play catch in terms of Newton’s THREE laws (not the law of universal gravitation). [7]

Atypical jetliner lands at a speed of 146 mi/h and decelerates at the rate of (10.4 mi/h)/s. if the jetliner travels at a constant speed of 146 mi/h for 1.5 s after landing before applying the brakes, what is the total displacement of the jetliner between touchdown on the runway and coming to rest?
