b
equal to zero.
c
greater in size than one of the forces.

equal in size to one of the forces.

Answer 1

Here are the answers to your questions:

3. The information provided does not specify the individual distances between points A, B, C, and D, making it impossible to calculate the total distance and displacement without additional data. Please provide the distances or coordinates for these points for a specific answer.

4. To find the average speed, you divide the total distance by the total time. Here, the object moves 10 meters in 5 seconds:

Average Speed = Distance / Time = 10 meters / 5 seconds = 2.0 m/s.

Correct answer: c 2.0 m/s

5. Your question about which segment of a graph represents the squirrel heading toward its nest cannot be answered without seeing the graph itself. Please provide more context or the graph to get the correct answer.

6. The answer depends on the information about the remote-controlled car, such as whether its speed is changing or if it is constant. Based on the options presented:

• If the car travels at a constant speed, it would either be at 6 m/s or 12 m/s.
• If it is speeding up, it would have either an increasing speed of 6 m/s or 12 m/s.

Without specific details about the car's movement, I can only suggest that if the speed is constant, typically one would refer to a speed like 6 m/s. If the information states that it travels at a constant speed, the correct answer would be: b It is traveling at a constant speed of 6 meters per second.

7. When balanced forces act on an object, they result in a net force of zero.

Correct answer: b equal to zero.
