A ball is dropped from a window 24 meters high. How long will it take ...
Calculating time taken for a ball to reach the ground
Given:
- Height of window = 24 meters
- Acceleration due to gravity = 9.8 m/s² (assuming no air resistance)
To find:
- Time taken by the ball to reach the ground
Formula:
- h = (1/2)gt² (where h = height, g = acceleration due to gravity, t = time taken)
Solution:
- Let's first find the time taken by the ball to reach the ground
- We know that the initial velocity of the ball is 0 (since it's dropped from rest)
- Using the formula h = (1/2)gt², we can find the time taken:
- 24 = (1/2)(9.8)t²
- 4.9t² = 24
- t² = 24/4.9
- t ≈ 2.2 seconds
- Therefore, it will take approximately 2.2 seconds for the ball to reach the ground.
Answer:
- Option (a) 2.2 s
Given:
- Height of window = 24 meters
- Acceleration due to gravity = 9.8 m/s² (assuming no air resistance)
To find:
- Time taken by the ball to reach the ground
Formula:
- h = (1/2)gt² (where h = height, g = acceleration due to gravity, t = time taken)
Solution:
- Let's first find the time taken by the ball to reach the ground
- We know that the initial velocity of the ball is 0 (since it's dropped from rest)
- Using the formula h = (1/2)gt², we can find the time taken:
- 24 = (1/2)(9.8)t²
- 4.9t² = 24
- t² = 24/4.9
- t ≈ 2.2 seconds
- Therefore, it will take approximately 2.2 seconds for the ball to reach the ground.
Answer:
- Option (a) 2.2 s
