Answer:
About 4.1323 meters.
Step-by-step explanation:
We can use the following kinematic equations:
We want to determine the distance the object has dropped after falling from rest and reaching an instantenous speed of 9 m/s.
We are given that the acceleration due to gravity is 9.8 m/s².
Using this fact and the first equation, find the time for which it took the object to reach 9 m/s. Note that the initial velocity is 0 m/s since the object started from rest.
To find how far the object dropped, we can use the second equation:
In conclusion, the object would have dropped about 4.1323 meters.
