Question

cassie is on a cruise for her vacation. she walks on the cruise ship while it sits idle in a bay. which statement describes how newtons third law of motion is involved in this interaction? if cassie exerts a 30 - pound force on the cruise ship as she walks, the cruise ship exerts a 30 - pound force on cassie. cassie will remain stationary until she pushes off the floor with her feet. when cassie walks across the ship, the cruise ship accelerates less than cassie because the cruise ship is more massive.

Explanation:

Newton's third - law states that for every action, there is an equal and opposite reaction. When Cassie exerts a force on the cruise ship while walking, the ship exerts an equal - magnitude force back on Cassie. The second statement is Newton's first law (inertia), and the third statement is related to Newton's second law ($F = ma$).

Answer:

If Cassie exerts a 30 - pound force on the cruise ship as she walks, the cruise ship exerts a 30 - pound force on Cassie.
