Question: A boy dropped a ball from a cliff. Find the ratio of distance fallen in the first 4 seconds to the distance fallen in the first 2 seconds by the ball.
Answer:
From the question, we know that
- Initial velocity = 0 ms^-1.
- Time taken = 2 s and 4 s.
- Acceleration = 10 ms^-2.
- Displacement = ?
Neatly done.
Now, to find the ratio of the time taken of two different falls, we will have to run the program twice as such.
Distance fallen in the first 2 seconds of the ball is 20 m.
Distance fallen in the first 4 seconds of the ball is 80 m.
Let's put them in the ratio as the question wants us to do it.
distance fallen in the first 4 seconds : distance fallen in the first 2 seconds = 80:20 = 4:1.
The answer is 4:1.
Easy to use, isn't it?
