When the displacement of a mass on a spring is 12 A, what percentage of the energy is kinetic energy?

Zolol [24]

Answer:

1.44%

Explanation:

The potential energy of a spring is given by

$U=\dfrac{1}{2}kx^2$

The kinetic energy is

$E=\dfrac{1}{2}kA^2$

Now x = 12 A

Applying in the first equation

$U=\dfrac{1}{2}k(12A)^2\\\Rightarrow U=\dfrac{1}{2}k144A^2\\\Rightarrow U=144\dfrac{1}{2}kA^2\\\Rightarrow U=144E$

The percentage would be 14400%

at $x=\dfrac{1}{2}A$ (makes more sense)

$U=\dfrac{1}{2}k(\dfrac{1}{2}A)^2\\\Rightarrow U=\dfrac{1}{2}k\dfrac{1}{4}A^2\\\Rightarrow U=\dfrac{1}{4}\times \dfrac{1}{2}kA^2\\\Rightarrow U=0.25E$

The percentage is 25 % of the kinetic energy

A driver without a seat belt getting thrown from the car in a collision is an example of Newton’s?

kupik [55]

Newton’s first law. An object stays in motion unless acted on by an external force or in this case the driver was in motion but the sudden crash stoped the car but not the driver

Identify how an electronic motor works.

Lena [83]

Large AC motors (used in things like factory machines) work in a slightly different way: they pass alternating current through opposing pairs of magnets to create a rotating magnetic field, which "induces" (creates) a magnetic field in the motor's rotor, causing it to spin around.
