Question

five stages - labeled a, b, c, d, and e - of an objects motion are represented by the position - time graph below. during which stage is the object moving with the greatest speed? position time tap on the buttons below to answer. select the one best answer a b c d e

Explanation:

Step1: Recall speed - slope relation

Speed is the magnitude of velocity, and on a position - time graph, the slope of the graph represents velocity. The steeper the slope, the greater the speed.

Step2: Analyze each stage

• Stage A: The graph has a steep negative - slope.
• Stage B: The slope is zero (horizontal line), so speed is zero.
• Stage C: The slope is positive but less steep than A.
• Stage D: The slope is zero (horizontal line), so speed is zero.
• Stage E: The slope is positive but less steep than A.

Answer:

A
