Most Upvoted Answer
A stone is projected horizontally from the top of a tower with a speed...
Given:
- Initial speed of the stone, u = 20 m/s
- Horizontal distance covered, x = 400 m
To find:
- Time of flight, t
Assumptions:
- The stone is projected horizontally, so there is no initial vertical velocity (uy = 0).
- Neglecting air resistance.
Analysis:
When the stone is projected horizontally, the only force acting on it is the force due to gravity. This force causes the stone to accelerate vertically downwards. The horizontal motion of the stone is uniform, as there are no horizontal forces acting on it.
Calculating time of flight:
The horizontal distance covered by the stone can be given by the equation:
x = uxt
Where,
x = Horizontal distance covered (400 m)
ux = Initial horizontal velocity (20 m/s)
t = Time of flight
Rearranging the equation, we get:
t = x / ux
Substituting the given values, we have:
t = 400 m / 20 m/s
t = 20 s
Therefore, the time of flight of the stone is 20 seconds.
Conclusion:
The stone takes 20 seconds to reach the ground when it is projected horizontally from the top of the tower with a speed of 20 m/s.
