Answer:
a = 0.581 m / s²
Explanation:
For this exercise we use Newton's second law that states that force is proportional to the mass and acceleration of the body
We write a frame of reference with the x axis in the direction of the floor
F = m a
a = F / m
Let's calculate
a = 25/43
a = 0.581 m / s²
The direction of the acceleration is the same direction of the force
The net force is 2.2 N at 80.9 degrees south of east
Explanation:
In order to find the net force, we have to resolve each force along the x-y direction, and then add the components in each direction.
Taking east as positive x-direction and north as positive y-direction, we have:
- First force:
- Second force:
Therefore, the components of the net force are
And so, the magnitude of the net force is
And the direction is
which means 80.9 degrees south of east.

Explanation:
Natural length of a spring is . The spring is streched by . The resultant energy of the spring is .
The potential energy of an ideal spring with spring constant and elongation is given by .
So, in the current problem, the natural length of the spring is not required to find the spring constant .
∴ The spring constant of the spring =

<span>Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force</span>
Answer:
<h2>10.52 kg</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
a is the acceleration
From the question we have
We have the final answer as
<h3>10.52 kg</h3>
