Energy Calculations

Physics
1 answer:
MaRussiya [10]3 years ago

Answer: 20,734.69 N/m

Explanation:

The elastic potential energy (ELPE) of the rubber band is given by

E=\frac{1}{2}kx^2

where

k is the spring constant

x = 0.035 m is the stretching of the rubber band

E = 12.7 J is the ELPE of the rubber band

Substituting the numbers and re-arranging the equation, we find

k=\frac{2E}{x^2}=\frac{2\cdot 12.7 J}{(0.035 m)^2}=20,734.69 N/m

A go cart with a mass of 60 kg is moving at a rate of 10 m/s. How much Kinetic Energy does the go cart have?
maria [59]

Answer:

<h2>3000 J</h2>

Explanation:

The kinetic energy of an object can be found by using the formula

k =  \frac{1}{2} m {v}^{2}  \\

m is the mass in kg

v is the velocity in m/s

From the question

m = 60 kg

v = 10 m/s

We have

k =  \frac{1}{2}  \times 60 \times  {10}^{2}  \\  = 30 \times 100 \\  = 3000

We have the final answer as

<h3>3000 J</h3>

Hope this helps you

A circular orbit would have an eccentricity of
vagabundo [1.1K]
<h2>Answer: zero (0)</h2>

Explanation:

The orbit of a body around another in space, is described by six orbital elements that determine its orientation, position, size and shape.

In the specific case of the shape of the orbit, this is determined by its <u>eccentricity</u>, which varies between 0 and 1 in the case of closed orbits (circle and ellipse). When the eccentricity is 0, the shape of the orbit is circular, when this value begins to vary until approaching 1 (without reaching 1), the shape of the orbit becomes more elliptical.

In this sense, a circular orbit will have an eccentriciy of zero.
