A young aspiring scientist decides to build a small robotic car. To ensure it travels precisely, she programs it to move 5 meters straight ahead, then turn right 90 degrees and move another 5 meters straight, and finally turn right 90 degrees again and move 5 meters straight. After this sequence, what would be the displacement of the car?

1. 15 m east of the starting point
2. 5 m to the right of the starting point
3. 0 m from the starting point
4. 10 m diagonally from the starting point

Answer: (b) 5 m to the right of the starting point

Study the given distance–time graph for Object A. Which of the following conclusions is INCORRECT based on the graph?

2. The object remains stationary between 3 and 4 minutes.
3. The steepest segment (between 4 and 5 minutes) shows maximum speed.
4. The motion is oscillatory between 2 and 6 minutes.

Answer: (d) The motion is oscillatory between 2 and 6 minutes.
