This problem involves Newton's 2nd Law which is: ∑F = ma, we have that the acting forces on the mass-spring system are: that correspond to the force of resistance on the mass by the action of the spring and that is an external force with unknown direction (that does not specify in the enounce).
For determinate we can use Hooke's Law given by the formula where correspond to the elastic constant of the spring and correspond to the relative displacement of the mass-spring system with respect of his rest state.
We know from the problem that an 15 Kg mass stretches the spring 1/3 m so we apply Hooke's law and obtain that...
Now we apply Newton's 2nd Law and obtaint that...
± =
Finally... ±
We know from the problem that there's not initial displacement and initial velocity, so... and
Finally the Initial Value Problem that models the situation describe by the problem is
To solve this problem, you must follow these steps:
1. Multiply the graph by -1 (That will reflect the function towards the -y axis).
2. Add 5. That will move the function upwards and you will obtain y=5 as its cut point with the y axis.
You can know the graph of a function by knowing the graph of the function "father" and applying the corresponding transformations, until turning it into the function studied.
The graph of the function f(x)=<span>|x| </span>has the shape of a cone that passes through the point (0,0).
Answer:
Step-by-step explanation:
6x+19.98=200
200-19.98=6x
X= 200-19.98/6
= solve for it.
