A 3.00-kg box is sliding along a frictionless horizontal surface with a speed of 1.8 m/s when it encounters a spring. (a) Determ

aniked [119]

Answer:

a) k= 3594,7 N/m

b) v= 0.55 m/s

Explanation:

a)
As the surface is horizontal, the only change in energy will be the change in kinetic energy, as the box comes to an stop after compressing the spring.
As we know that the surface is frictionless also, this change in kinetic energy must be equal to the change in the elastic potential energy of the spring.
So we can write the following equality:

$\Delta K = \Delta U$

where $\Delta K = \frac{1}{2}*m*v^{2}$

and $\Delta U = \frac{1}{2} * k* \Delta x^{2}$

Simplifying and replacing by the values, we get:

$3.00 kg* (1.8 m/s)^{2} = k* (0.052 m) ^{2}$

Solving for k:

$k = \frac{3.00kg*(1.8m/s)^{2} }{(0.052m)^{2}} = 3594.7 N/m$

k = 3594.7 N/m

b)
For this part, we can just apply the same equality, replacing the value of k by the one we got, and solving for the initial speed v:

$v = \sqrt{\frac{k*\Delta x^{2}}{m} } = \sqrt{\frac{3594.7N/m*(0.016m)^{2} }{3.00kg}} = 0.55 m/s$

v = 0.55 m/s

A simple generator is used to generate a peak output voltage of 19.0 V . The square armature consists of windings that are 6.65

One of the efficient concepts that can help us find the number of turns of the cable is through the concept of induced voltage or electromotive force given by Faraday's law. The electromotive force or emf can be described as,

$\epsilon = NBA\omega$
