Answer 1

Answer on Question #42588 – Physics - Mechanics | Kinematics | Dynamics

an electric train is moving in the velocity of 120km/hr. how much distance it will move in 30sec,

Solution:

$$V = 120 \frac{\text{km}}{\text{hr}} = 33.3 \frac{\text{m}}{\text{s}} - \text{velocity of the train};$$ $$t = 30\text{s} - \text{time of movement};$$

Formula for the distance:

$$\text{distance} = \text{velocity} \cdot \text{time} = 33.3 \frac{\text{m}}{\text{s}} \cdot 30\text{s} = 999\text{m}$$

Answer: traveled distance is equal to 999m.
