while on vacation, aubrey took a helicopter ride to an island. the helicopter lifted off, cruised at the desired altitude, rose to go over a mountain, and descended on the other side of the mountain to the island’s landing pad. which graph could show aubrey’s elevation over time?

while on vacation, aubrey took a helicopter ride to an island. the helicopter lifted off, cruised at the desired altitude, rose to go over a mountain, and descended on the other side of the mountain to the island’s landing pad. which graph could show aubrey’s elevation over time?

Answer

Explanation:

Step1: Analyze the helicopter's motion phases

The helicopter has four phases: lift - off (elevation increases with time), cruise (elevation is constant), rise over mountain (elevation increases), and descend to landing (elevation decreases to near 0).

Step2: Evaluate each graph

  • Top - left graph: Only has increase, peak, and decrease. No constant cruise phase. Eliminate.
  • Top - right graph: Has increase, peak, decrease, constant, and then decrease. The constant phase is after descending, which does not match the scenario. Eliminate.
  • Bottom - left graph: First, elevation increases (lift - off), then constant (cruise), then increase (rise over mountain), then decrease (descend to landing). This matches the motion phases.
  • Bottom - right graph: Increase, constant, then decrease. No rise over mountain phase. Eliminate.

Answer:

The Bottom - Left Graph
