This is observational learning because Ian observed that his peers waited in the cafeteria until the first bell rings. He decided to imitate them.
Time taken to reach water :

Now, initial vertical speed , u = 0 m/s.
By equation of motion :

Here, a = g = acceleration due to gravity = 9.8 m/s².
So,

Therefore, the height of the bridge is 3.46 m.
Hence, this is the required solution.
Answer:
Difference in experimental data.
Explanation:
There is difference of experimental value between the experiment that is performed on the earth and on the international space station because presence of gravity. The result of the experiment on the earth is different due to the presence of gravity that contributes in the result of the experiment as compared to international space station where no gravity is present so there is high difference of the numerical value of the result of both experiments of earth and international space station.
