Question

Может ли лодка быть неподвижной относительно берегов реки хотя гребцы и работают веслами. Будет ли при этом лодка неподвижна относительно воды.

Answer 1

Может, если сила работы веслами компенсируется силой течения реки. Лодка при этом не будет неподвижной относительно воды.

Answer 2

Can a boat be stationary relative to the riverbank while the rowers are rowing? Will the boat be stationary relative to the water?

When rowers are rowing, it is possible for a boat to be stationary relative to the riverbank while still moving relative to the water. This can be achieved by rowing against the current of the river. The rowers' efforts can counteract the force of the current, allowing the boat to remain in the same position relative to the riverbank.

However, it's important to note that the boat will not be stationary relative to the water. The rowers' actions will propel the boat forward, causing it to move through the water. The boat's movement relative to the water will depend on the rowers' strength and the force of the river's current.

In summary, while the boat can be stationary relative to the riverbank, it will not be stationary relative to the water. The rowers' efforts will result in the boat moving through the water, even if it remains in the same position relative to the riverbank.
