Question

speed problems
match the graph that best fits the motion from the data table.

time (sec)	distance (m)
5	20
10	40
15	20
20	0

Explanation:

Step1: Analyze distance - time relationship

From 0 - 10 seconds, distance increases linearly as time increases. From 10 - 15 seconds, distance decreases. From 15 - 20 seconds, distance decreases to 0.

Step2: Match with graphs

The first graph shows distance increasing, then decreasing back to 0 which matches the data in the table.

Answer:

The first graph (top - left graph)
