To solve this problem it is necessary to apply the concepts related to the kinematic equations of movement description, which determine the velocity, such as the displacement of a particle as a function of time, that is to say

Where,
x = Displacement
v = Velocity
t = Time
Our values are given as,


Replacing we have that,



Therefore the distance from Earth to the Moon is 399.000 km
Oh my lord lol I was do ready to help then I saw numbers
X- points away from the charge
y- points in the direction of the force on the positive charge
z- points toward the charge
The statements that are held true with regards to the static equilibrium of bodies are:
<span>The net torque acting on the object must equal zero
</span><span>The net torque on the object does not have to be zero if the net force on the object is zero
Furthermore, when a body is in a state of static equilibrium, the summation of all forces, either vertically or horizontally, must be equal to zero. </span>
Answer:
the speed of the block when it reaches point B is 14 m/s
Explanation:
Given that:
mass of the block slides = 1.5 - kg
height = 10 m
Force constant = 200 N/m
distance of rough surface patch = 20 m
coefficient of kinetic friction = 0.15
In order to determine the speed of the block when it reaches point B.
We consider the equation for the energy conservation in the system which can be represented by:






v = 14 m/s
Thus; the speed of the block when it reaches point B is 14 m/s
