Question

Поезд едет со скоростью v=10 м/с . Пассажир едет против движения поезда со скоростью 1 м/с, относительно вагона. Определите скорость пассажира относительно земли

Answer 1

Скорость относительно Земли 10-1=9 м/с

Answer 2

Calculation of Passenger's Speed Relative to the Earth

To determine the passenger's speed relative to the Earth, we need to consider the velocities of both the train and the passenger.

Given: - Velocity of the train (v) = 10 m/s (source - Velocity of the passenger relative to the train (v_p) = 1 m/s (source

To find the passenger's speed relative to the Earth, we can use the principle of relative motion. The passenger's velocity relative to the Earth (v_e) can be calculated by adding the velocities of the passenger and the train:

v_e = v + v_p

Substituting the given values:

v_e = 10 m/s + 1 m/s = 11 m/s

Therefore, the passenger's speed relative to the Earth is 11 m/s.
