Question

Поезд движется со скоростью 72 км в час. Найдите его перемещение за 30 секунд. СРОЧНООО

Answer 1

s=v*t

v=72*10^3 м/3600 с= 20 м/c

s=20 м/с*30c= 600 м

Ответ: s=600 м

Answer 2

V=20м\с
t=30с
s=v*t=20*30=600m

Answer 3

Calculation of the Train's Displacement

To find the displacement of the train, we need to calculate the distance it travels in 30 seconds.

Given: - Speed of the train: 72 km/h

To calculate the displacement, we can use the formula:

Displacement = Speed × Time

Converting the speed from km/h to m/s: - 1 km/h = 1000 m/3600 s = 5/18 m/s

Converting the time from seconds to hours: - 30 seconds = 30/3600 hours = 1/120 hours

Substituting the values into the formula:

Displacement = (72 km/h) × (5/18 m/s) × (1/120 hours)

Calculating the displacement:

Displacement = (72 × 5 × 1) / (18 × 120) km

Simplifying the calculation:

Displacement = 0.1 km

Therefore, the displacement of the train in 30 seconds is 0.1 kilometers.
