Answer 1

Here are the answers:

1. Amelia swims 600 m at 8 m/s → t = 600 / 8 = 75 seconds. (Answer: 75 seconds)

2. When balanced forces act on an object, the net force is equal to zero. (Answer: equal to zero)

3. I can’t determine the net force without the picture or the magnitudes/directions of the pushes. Please upload the diagram or tell me the force values and directions.

4. An object that is accelerating may be: changing direction; traveling at a constant speed (if direction changes, e.g., circular motion); slowing down; gaining speed. (Do not choose “not moving.”)

5. Compute speeds (km/h) = distance / time:
- Gray fox: 73 / 1.05 ≈ 69.5
- Gazelle: 68 / 0.85 = 80
- Rabbit: 70 / 1.25 = 56
- Cheetah: 85 / 0.75 ≈ 113.33
- Giraffe: 60 / 1.15 ≈ 52.17
- Antelope: 93 / 0.95 ≈ 97.89

Greatest speed: cheetah. (Answer: cheetah)

If you provide the cart diagram or the force values for question 3, I’ll give that answer too.
