.HCM A group of students is determining the resulting displacement in a treasure hunt lab activity. The following directions are given to find the
treasure:
• travel 10 steps north
5 steps west
• 2 steps south
• finally, 1 step west
Which of the following magnitudes of the resultant displacement and explanation is correct?
Exhibits

magnitude and direction

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.
