which statements describe a situation with a displacement of zero? check all that apply. traveling south for 30 miles, then turning west and traveling another 30 miles riding on a ferris wheel whose entrance and exit are the same walking around the block, starting from and ending at the same house riding on an escalator from the bottom floor to the top floor running exactly one lap around a racetrack

Answer

Brief Explanations:

Displacement is the straight - line distance from the initial to the final position. If the initial and final positions are the same, displacement is zero. For traveling south then west, initial and final positions are different. For a Ferris wheel with same entrance and exit, initial = final. For walking around a block and ending at the same house, initial = final. For an escalator from bottom to top, initial ≠ final. For running one lap around a racetrack, initial = final.

Answer:

  • riding on a Ferris wheel whose entrance and exit are the same
  • walking around the block, starting from and ending at the same house
  • running exactly one lap around a racetrack
