Yes it would
Explanation:
As the arrow and the orange are in the same position initially, vertically speaking. They are also subjected to the same gravitational acceleration g only in the vertical direction. They also start their motion at the same time. So their equation of motion can be written as
Where h is the initial height of both of them. Since their g, h, and t are the same, their vertical position must be the same at the same time. As the arrows progress horizontally, it would hit the orange.
The expected time period between the observations of lightning and thunder would be 22.5 s.
How to calculate the time of sound waves?
The time taken by sound to reach a certain position can be calculated by the speed formula,
Where,
- speed = 0.343 km/s
- distance = 7.5 km
- time = ?
Put the values in the formula,
Therefore, the expected time period between the observations of lightning and thunder would be 22.5 s.
