Question

question 5 1 pts a person is in a canoe on a calm lake. if they threw a heavy stone into the water in front of them, what would happen? the canoe would remain still because it is too heavy. the canoe would move backward a bit. the canoe would move forward and keep going. the canoe would move forward a bit.

Explanation:

Step1: Apply law of conservation of momentum

The initial momentum of the person - canoe - stone system is zero (as they are at rest). When the stone is thrown forward, according to the law of conservation of momentum, the system's total momentum must remain zero. So, the canoe and the person must move in the opposite direction to the stone's motion.

Step2: Analyze the motion

The canoe will move backward a bit to balance the forward - moving momentum of the stone. Once the stone is in the water and the action of throwing is over, there is no continuous force to keep the canoe moving.

Answer:

The canoe would move backward a bit.
