The question is incomplete. Here is the complete question.
A spring with a spring constant of 68 newtons per meter hangs from a ceiling. Whena 12-newton downward force is applied to the free end of the spring, the spring streches a total distance of
(1) 5.7m
(2) 0.59m
(3) 820m
(4) 0.18m
Answer: (4) 0.18 m
Explanation: The force necessary to compress or extend a spring by a displacement is directly proportional to that distance and the spring's constant. This relationship is stated by a principle called <u>Hooke's</u> <u>Law</u>:
k is spring constant, which shows how stiff the spring is and so, is characteristic of each spring;
x is total displacement;
The negative sign on the formula indicates the restoring force caused by the spring is in opposite direction related to the force and it is why the displacement occurs.
So, for the spring in the question above:
When a 12 N force is applied to the spring, it streches 0.18 m.
The motion of an apple when it falls from a tree is
b) Accelerating
The motion of apple is when it falls from a tree is the case of free fall.
During free fall , the initial velocity of the apple or any object is zero but it gains some velocity due to gravitatonal acceleration .
Answer:
the distance between point a and b and the time it takes to get from a to b.
Explanation:
d/t =v
Answer:
<h3>The answer is 22.26 N</h3>
Explanation:
The force acting on an object given the mass and acceleration we use the formula
<h3>force = mass × acceleration</h3>
From the question
mass = 5.3 kg
acceleration = 4.2 m/s²
We have
force = 5.3 × 4.2
We have the final answer as
<h3>22.26 N</h3>
