Question

Question 2 (1 point) d According to Newton's Laws of Motion, if I throw a baseball in outer space - far from any other object- how will that ball move over time? (For the sake of this problem, let's neglect my mass) After the force of my hand no longer acts on the ball: the ball will move forward, but it will gradually slow down and come to a stop once the force of my hand no longer acts on it, the ball will stop almost immediately the ball will continue moving with a constant velocity lat the same speed in the same direction) unless an outside force acts on it after my hand no longer acts on the ball, it will start moving faster and faster Save

Explanation / Answer

Ans

Question: 2 The ball is thrown in outer space far from any objects, hence no gravitation force acts on the ball (your mass is also ignored). So no net force acts on the ball once it's thrown, hence by Newton's second law, the acceleration of the ball = 0 m/s^2. So, ball will continue moving constant velocity(at the same speed in the same direction) unless an outside force acts on the ball.

hence option 3 from the top is correct.

------------------------------------

Question 4:

Any frame which has no acceleration relative to earth would be inertial reference frame.

so these would be the inertial frame of reference:

1) the inside of a gymnasium.

2) the inside of a train moving east at 30 m/s (constant velcoity hence acceleration = 0m/s^2).

3) the inside of an airplane moving west at 120 m/s.
