Solution
Solution Steps
Step 1: Analyze the graph
The graph shows the position of objects B, C, and D as a function of time. A straight line on a position-time graph indicates constant velocity (zero acceleration). A curved line indicates changing velocity, and therefore acceleration.
Step 2: Determine if C accelerated.
Line C is curved, indicating that object C accelerated.
