Answer:
“Speed” is the magnitude of the velocity vector. It is part that quantifies the distance traveled per unit time. “Acceleration” is the change in the velocity vector.
Explanation:
Hope this helps!!
We have negative acceleration when an object projected upwards, while positive acceleration is a free fall.
The circulatory system sends nutrients to the body's cells.
Answer:
6 rad/s
Explanation:
In a spring the angular frequency is calculated as follows:
where is the angular frequency, is the mass of the object in this case , and is the constant of the spring.
To calculate the angular frequency, first we need to find the constant which is calculated as follows:
Where is the force: , and is the distance from the equilibrium position: .
Thus the spring constant:
And now we do have everything necessary to calculate the angular frequency:
the angular frequency of the oscillation is 6 rad/s
