Here are the answers to the questions you provided:
8. Which of the following surfaces would have the lowest amount of friction?
**d. Ice**
Ice typically has much lower friction compared to glass, sand, and wood.
9. A car engine provides 2500 N of force for a car that has a mass 1000 kg. If an engineer develops a new chassis for a car that is half as massive, what is the acceleration of the car with the new chassis?
**b. 5 m/s²**
The new mass would be 500 kg. Using Newton's second law (F = ma), we have:
\( a = \frac{F}{m} = \frac{2500 \, N}{500 \, kg} = 5 \, m/s² \).
10. He’s riding his skateboard down a ramp. Assume that his acceleration is 0.8 m/s². How much force does it take for him to accelerate at this rate? Zeke has a mass of 50 kg.
**a. 40 N**
Using Newton's second law (F = ma):
\( F = 50 \, kg \times 0.8 \, m/s² = 40 \, N \).
11. According to Newton's Third Law, if a hammer puts a force of 200 N on a nail, how much force does the nail put back on the hammer?
**a. 200 N**
According to Newton's Third Law, for every action, there is an equal and opposite reaction.
12. Two bodies in contact experience forces in ________.
**b. Opposite directions**
Forces between two bodies in contact always act in opposite directions.
13. Dansby Swanson hits a ball with a force of 5 N. What force does the bat experience?
**b. 5 N**
The bat experiences an equal and opposite force of 5 N due to Newton's Third Law.
