Question

You are out in your sail-boat and the wind stops blowing when you arr 20 meters from shore- you are stuck. You have no paddles in the boat and are not able to reach the water to push with your body use Newton's third law of motion to identify what you can do to get to shore using the box of apples you find in the boat

Answer 1

Answer:

According to Newton's third law, throwing the apples in the opposite direction to the shore with a force, F₁, one after the other, repeatedly, pushes the both towards the shore with a force also equal to F₂ until the boat reaches the shore

Explanation:

The given parameters are;

The distance of the boat from the shore = 20 meters

The available propulsion devices = A box of apples

According to Newton's third law of motion states that action and reaction are equal and opposite

Therefore, according to Newton's third law, by throwing the apple into the  water in the opposite direction to the shore, such that each apple of mass m₁, is given an acceleration a₁, will result in a force, F₁ = m₁a₁ in the direction away from the shore

According to Newton's third law of motion, the force F₁, will result in an opposite reaction force F₂ in the direction of the shore, such that as F₁ is made large by giving a higher acceleration, a₁ the apples, reaction force on the occupant of the boat , who is throwing the apple, F₂, increases

F₁ = -F₂

Where;

F₂ = m₂·a₂

a₂ = The acceleration of the boat and the occupant

m₂ = The mass of the boat and the occupant

Given that the mass, m₂, is constant, the acceleration of the boat and occupant, a₂, increases as F₁ increases, increasing the speed of the boat from zero to positive value above zero m/s and the boat moves towards the shore
