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? cassie will remain stationary until she pushes off the floor with her feet. if cassie exerts a 30 - pound force on the cruise ship as she walks, the cruise ship exerts a 30 - pound force on cassie. 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 force back on her. The first statement is Newton's first law (inertia), and the third statement is 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.
