A 2-kg bowling ball is 1 meter off the ground on a post when it falls just before it reaches ground it is travelling 4.4 m/s ass
2 answers:
Answer : (C) "mechanical energy is conserved".
Explanation :
It is given that :
Mass of the ball, m = 2 kg
Velocity, v = 4.4 m/s
Height, h = 1 m
Mechanical energy is the sum of kinetic energy and the potential energy. It is related with the position and the motion of the body.
So,
In this case, the mechanical energy or the total energy of the ball remains conserved. This is termed as conservation of Mechanical energy.
So, the correct option is (C) "mechanical energy is conserved and it is equal to 38.96 J".

Explanation:
The work of force 2 will be given by the vectorial equation . We know the value of
and have information about its movement, which relates to the net force
.
About this movement we can obtain the acceleration using the equation . Since it departs from rest we have
.
And then using Newton's 2dn Law we can obtain the net force F=ma, thus we will have
And we had the work done by force 2 as:
(The sign will be given algebraically since we take positive the direction to the right.)
With our values:
<em>Another (shorter but maybe less intuitive way for someone who is learning) way of doing this would have been to say that the work done by both forces would be equal to the variation of kinetic energy:</em>
<em></em>
<em>Which leads us to the previous equation straightforwardly.</em>
Answer:
Explanation:
Since the wire is infinitely long, we will use Gauss' Law:
We will draw an imaginary cylindrical surface with height h around the wire. The electric flux through the imaginary surface will be equal to the net charge inside the surface.
In that case, the net charge inside the imaginary surface will be the portion of wire with height h. Then the charge of that portion will be equal to
The left-hand side of the Gauss' Law is the flux through the imaginary surface. Since we choose our surface as a cylinder, of which we know the area, we do not have to take the surface integral.
where R is the radius of the imaginary cylinder.
Finally, Gauss' Law gives
The vector expression is
As you can see, the electric field is independent from the height h, since that is merely an imaginary cylinder to apply Gauss' Law. In the end, what matters is the charge density of the wire and the distance from the wire.
