Answer:
t = 3 [s]
Explanation:
To solve this problem we must use the following equation of kinematics.

where:
Vf = final velocity [m/s]
Vo = initial velocity = 15 [m/s]
g = gravity acceleration = 10 [m/s²]
t = time [s]
Now replacing we have:
![0 = 15 -10*t\\10*t=15\\t= 1.5[s]](https://tex.z-dn.net/?f=0%20%3D%2015%20-10%2At%5C%5C10%2At%3D15%5C%5Ct%3D%201.5%5Bs%5D)
Note: In the equation above the gravity acceleration is negative, because the movement of the ball bearing is pointing againts the gravity acceleration.
The time calculated is only when the ball bearing reaches the highest elevation, and it will take the same time for descending, therefore the total time is:
t = 1.5 + 1.5 = 3 [s]
Considering the volume of a rectangle, the volume of the tissue box is 3,239.1 cm³.
<h3>What is volume</h3>
Volume is a scalar-type metric quantity that is defined as the extension in three dimensions of a region of space. In other words, the volume corresponds to the space that the shape occupies.
<h3>Volume of a rectangle</h3>
To calculate the volume of a rectangle, it is necessary to multiply its 3 dimensions: length ×width×height. Volume is expressed in cubic units.
<h3>Volume of the tissue box</h3>
In this case, you know:
- Length: 11.8 cm
- Width: 12.2 cm
- Height: 22.5 cm
Replacing in the definition of volume of a rectangle:
Volume of the tissue box= length ×width×height
Volume of the tissue box= 11.8 cm× 12.2 cm× 22.5 cm
Solving:
<u><em>Volume of the tissue box= 3,239.1 cm³</em></u>
Finally, the volume of the tissue box is 3,239.1 cm³.

Explanation:
When spring is used as a lift tool
so the mass suspended on it will have spring force on it
So as per the force equation of mass we can say

now net force on the mass is


here we have

now we have
