Answer:
68.6 m/s
Step-by-step explanation:
The speed at a given time is the derivative of the height at that time.
dh/dt = -9.8t
At t=7, the speed is ...
-9.8(7) = -68.6 . . . . . meters per second (downward)
The speed is 68.6 meters per second.
_____
<em>Additional comment</em>
Height is considered to be positive in the up direction, so velocity and acceleration are also positive in the up direction. The derivative of height will be the velocity. Its negative sign in this case indicates the object is moving in the downward direction. The speed is the magnitude (absolute value) of the velocity.
Answer:
<h3>Total 20 boxes are there. </h3>
Step-by-step explanation:
Total number of shelves in a warehouse = 5 shelves.
Each shelve either can hold maximum 8 boxes with their lengths or can hold 4 boxes with their heights.
So, in that case only 4 boxes could be hold in each of 5 shelves because only 4 boxes could be fit with their heights.
Therefore, total number of boxes = 5 × 4 = 20 boxes .
<h3>Therefore, total 20 boxes are there. </h3>
