an object is placed at 0 on a number line. it moves 3 units to the right, then 4 units to the left, and then 6 units to the right. what is the displacement of the object?\n1\n5\n7\n13
Answer
Explanation:
Step1: Define right - movement as positive
Moving 3 units to the right is + 3.
Step2: Define left - movement as negative
Moving 4 units to the left is - 4.
Step3: Add the third movement
Moving 6 units to the right is + 6.
Step4: Calculate the displacement
Displacement = 3+( - 4)+6 = 3 - 4+6 = 5.
