If the runner is running in a circular track then yes when something or someone is moving in a circular motion at a constant speed they are indeed accelerating. They’re accelerating because the direction of the velocity vector is changing
Answer:
<em>Answer: Work equals force times distance. 3,000 J</em>
Explanation:
Work Done By A Force
When some force is applied and a displacement is achieved, the work done by the force is given by
Note that the work is a scalar magnitude as the result of the dot-product of two vectors. If the force and the displacement are parallel, then the vectors can be replaced as its magnitudes F,x and the work is
The dot product becomes a simple arithmetic product, i.e force times distance.
Sara weighs 500 Nw and she climbs up a 6 meter set of stairs. She needs to lift her weight up, so the force is the weight and the distance is the height of the stairs, thus
Answer: Work equals force times distance. 3,000 J
Answer:
The description of the frame of reference is characterized below.
Explanation:
- Accuracy, as well as regression coefficients, seem to be the new standard measures besides summing up the validity of the developed modeling techniques.
- Classification accuracy unfortunately due to the presuppositions established by professionals on data sources with such an equitable classification process on supervised learning mostly with completely skewed category apportionment

Answer:
the spring constant is -89.2857 n/m
Explanation:
The computation of the spring constant is shown below:
As we know that
Force in newtons = Spring constant × amount of extension
F = -k × x
where
F = 25 N
And, x = 0.280m
So, the spring constant would 2
= 25N ÷ 0.280 m
= -89.2857 n/m
Hence the spring constant is -89.2857 n/m
