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.
Answer:
the answer is 1/y^3
Step-by-step explanation:
when ever there is an negative exponent you flip it and put the base and exponent in a fraction under 1 hope this helps
2/3 of 18 is 12, so peter gave 12 cookies to his friend.
The answer is as follow
sin60° = 400√3 / H1, implies H1= 400√3 / sin60° <span>
sin30° = </span>400√3 / H2, implies H2= 400√3 / sin30° <span>
and the if the distance is D,
so we can find D such that D= H2 - H1=</span>400√3 / sin30° - 400√3 / <span>sin60°
D= </span>400√3(1/sin30° - 1/ sin60°)=400√3(2-1.15)=338.11<span>√3</span>
