Answer:
D. Synthetic polymers are inexpensive to produce.
Explanation:
Hailey should include that synthetic polymers are inexpensive to produce as a benefit of synthetic polymers.
Synthetic polymers are artificially produced. These polymers come about from petroleum oil. Their hydrocarbons are industrially worked to produce the long chain hydrocarbons to form polymers.
Most of these polymers are very cheap to produce and does not cost too much. This is why they almost found everywhere.

Answer:
Force must be applied to m₁ to move the group of rocks from the road at 0.250 m/s² = 436 N
Explanation:
Total force required = Mass x Acceleration,
F = ma
Here we need to consider the system as combine, total mass need to be considered.
Total mass, a = m₁+m₂+m₃ = 584 + 838 + 322 = 1744 kg
We need to accelerate the group of rocks from the road at 0.250 m/s²
That is acceleration, a = 0.250 m/s²
Force required, F = ma = 1744 x 0.25 = 436 N
Force must be applied to m₁ to move the group of rocks from the road at 0.250 m/s² = 436 N
