Question

7. Қайықтың үстінде отырған оқушы қайықты тынық сумен салыстырғанда 1,2м/с жылдамдықпен еседі. Егер су ағысының жылдамдығы 1,2м/с болса, қайықтың жағамен салыстырғандағы жылдамдығы қандай? Қайық судың ағысымен және ағысқа қарсы жүзеді деп есептеңдер.

Answer 1

The Speed of the Boat Relative to the Water

When a boat is moving on the surface of the water, its speed can be measured in relation to the water or in relation to the ground. The speed of the boat relative to the water is called the boat's speed through the water. In this case, the boat's speed through the water is given as 1.2 m/s.

The Speed of the Boat Relative to the Ground

To determine the speed of the boat relative to the ground, we need to consider the effect of the current. If the current is flowing in the same direction as the boat, it will add to the boat's speed through the water. Conversely, if the current is flowing in the opposite direction, it will subtract from the boat's speed through the water.

Calculating the Boat's Speed Relative to the Ground

To calculate the boat's speed relative to the ground, we need to know the speed of the current. However, this information is not provided in the question. Without the speed of the current, we cannot determine the exact speed of the boat relative to the ground.

Conclusion

In summary, the boat's speed through the water is given as 1.2 m/s. However, without knowing the speed of the current, we cannot determine the boat's speed relative to the ground.
