question 13

Multiple Choice

On a horizontal frictionless floor,a worker of weight 0.900 kN pushes horizontally with a force of 0.200 kN on a box weighing 1.80 kN.As a result of this push,which statement could be true?

• A) The box will not move because the push is less than its weight.
• B) The worker and box will both have an acceleration of 1.08 m/s², but in opposite directions.
• C) The worker and box will both have an acceleration of 2.17 m/s², but in opposite directions.
• D) The worker will accelerate at 1.08 m/s² and the box will accelerate at 2.17 m/s², but in opposite directions.
• E) The worker will accelerate at 2.17 m/s² and the box will accelerate at 1.08 m/s², but in opposite directions.
