Answer:
The reason one must apply a force to a box in order for the box to move is to overcome the friction generated by the box against the plane the box is sitting.
The box at rest has zero friction against the surface on which it sits. Once a force is applied, a box's movement is resisted by the friction created from contact with the surface.
In order for the box to move, one must generate more force than is being generated by the friction of the surface onto the box, allowing the box to move.

Answer:
about 0.20
Step-by-step explanation:
The speed, acceleration, and distance satisfy the equation ...
v² = 2ad
So the acceleration is ...
a = v²/(2d) = (6 m/s)²/(2×9 m) = 2 m/s²
If we take the acceleration due to gravity to be 9.8 m/s², the coefficient of kinetic friction is the ratio of these:
k = (2 m/s²)/(9.8 m/s²) ≈ 0.20
Recall your d = rt, distance = rate * time.
let's say the rate of speed for Kala was "r" on the way over to the mountains.
Now, on the way over, it took 8 hours due to heavy traffic, whilst on the way back it took only 5 hours since there was no traffic.
The distance covered, say "d" miles, is the same on the way over as well as on the way back.
Answer
x = − 4,− 10
Step-by-step explanation:
Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
<h3>
<u>Explanation</u></h3>
- Calculate the slope by using rise over run with given coordinate points.
- From the slope-intercept form.
Because the graph passes origin point (0,0). Therefore the value of b is 0.
