Question

Человек бежит со скоростью 5м/с относительно палубы теплохода в направлении, противоположном направлению движения теплохода. скорость теплохода относительно пристани равна 54 км/ч. определите скорость человека относительно пристани

Answer 1

Скорость человека относительно пристани =15м/c-5м/c (54км/x=15м/c)

 

Answer 2

Calculation of the Person's Speed Relative to the Pier

To determine the speed of the person relative to the pier, we need to consider the speed of the person relative to the ship and the speed of the ship relative to the pier.

Given information: - Speed of the person relative to the ship: 5 m/s (against the direction of the ship's movement) - Speed of the ship relative to the pier: 54 km/h

To calculate the speed of the person relative to the pier, we need to convert the speed of the ship from km/h to m/s.

Converting the speed of the ship: - 54 km/h = 54,000 m/3,600 s = 15 m/s.

Now, we can calculate the speed of the person relative to the pier by adding the speed of the person relative to the ship and the speed of the ship relative to the pier.

Calculating the speed of the person relative to the pier: - Speed of the person relative to the pier = Speed of the person relative to the ship + Speed of the ship relative to the pier - Speed of the person relative to the pier = 5 m/s + 15 m/s = 20 m/s.

Therefore, the speed of the person relative to the pier is 20 m/s.

Please note that this calculation assumes that the speeds are constant and there are no other factors affecting the motion of the person and the ship.
