You are standing in a boat. Which of the following strategies will make the boat start moving? Check all that apply.

a. Pushing its mast
b. Throwing some cargo out of the boat
c. Pushing the front of the boat
d. Pushing another passenger

Respuesta :

Answer:

b. Throwing some cargo out of the boat

Explanation:

Using the Newton's third law of motion which states that every action has an equal and opposite reaction.

So when we are on the boat and we throw some mass in a direction away from the boat out of it then we are imparting the force to the floating boat by the law of conservation of momentum as well.

The relation can be mathematically expressed as:

[tex]m_c.v_c=m_b.v_b[/tex]

where:

[tex]m_c=[/tex] mass of the cargo

[tex]v_c=[/tex] velocity of throwing the cargo

[tex]m_b=[/tex] mass of the whole boat including all that floats on it

[tex]v_b=[/tex] velocity of the boat system

Throwing some cargo out of the boat will make the boat start moving.

Newton's third law of motion;

This law states that action and reaction are equal and opposite.

  • The force apply in pushing the mast, or another passenger in the boat will be equal to the force they will push back at you.
  • The two forces will cancel out and the boat will remain stationary.

Principle of conservation of linear momentum;

The total momentum of an isolated system is always conserved.

Throwing some cargo out of the boat will change the velocity of the cargo initially at rest and to conserve the linear momentum, the velocity of the boat will change as well.

Thus, throwing some cargo out of the boat will make the boat start moving.
