Answer:
∅=10.7°
Explanation:
In parabolic motion the position on the x-axis can be found like this.
Where we clear the time.
The position on the y-axis can be found as well.
replacing time.
Now we use the quadratic equation to find the tangent of the angle.
Finally we use the arc tangent function to find the angle.
We choose the second angle because it adapts to the situation described, that is the minimum angle.
M= Height of image/height of the object
If, M>1, then height of image>height of object.
And therefore, image is larger than the object.
A weight explanation is the volume of density of a particular substance has to be weight…
Answer:
<em>No, a rigid body cannot experience any acceleration when the resultant force acting on the body is zero.</em>
Explanation:
If the net force on a body is zero, then it means that all the forces acting on the body are balanced and cancel out one another. This sate of equilibrium can be static equilibrium (like that of a rigid body), or dynamic equilibrium (that of a car moving with constant velocity)
For a body under this type of equilibrium,
ΣF = 0 ...1
where ΣF is the resultant force (total effective force due to all the forces acting on the body)
For a body to accelerate, there must be a force acting on it. The acceleration of a body is proportional to the force applied, for a constant mass of the body. The relationship between the net force and mass is given as
ΣF = ma ...2
where m is the mass of the body
a is the acceleration of the body
Substituting equation 2 into equation 1, we have
0 = ma
therefore,
a = 0
this means that<em> if the resultant force acting on a rigid body is zero, then there won't be any force available to produce acceleration on the body.</em>
