Question

Величина скорости корабля в стоячей воде 3,5 м/с. Значение скорости движения реки 0,7 м/с. В ответе запиши значение скорости по модулю, с которой станет перемещаться корабль относительно берега, если корабль плывёт по течению реки. Даю 90 баллов. пжпжпжпжпжпж

Answer 1

V₁=3,5 м/с      скорость корабля относительно берега, когда он 
v₂=0,7 м/с         плывет по течению реки равна:
_________           v=v₁+v₂=3,5+0,7=4,2 м/с;
v-?                        Ответ: v=4,2 м/с.

Answer 2

Calculation of Ship's Speed Relative to the Shore

To calculate the speed at which the ship will move relative to the shore when it is moving with the current of the river, we need to consider the velocities of the ship and the river.

Given: - Speed of the ship in still water: 3.5 m/s - Speed of the river current: 0.7 m/s

To find the speed at which the ship will move relative to the shore, we can use the concept of vector addition. The speed of the ship relative to the shore can be calculated by adding the speed of the ship in still water to the speed of the river current.

Using the formula for vector addition, we have:

Speed of the ship relative to the shore = Speed of the ship in still water + Speed of the river current

Substituting the given values:

Speed of the ship relative to the shore = 3.5 m/s + 0.7 m/s = 4.2 m/s

Therefore, the ship will move with a speed of 4.2 m/s relative to the shore when it is moving with the current of the river.
