Answer:
A)196J
B)-208J
C)3467J
Step-by-step explanation:
We are given that a 20 kg cylindrical mass is dropped onto the mat from a height of 1 m above the mat. During the impact, the cylinder’s vertical velocity reaches zero at the instant the mat has compressed to only 4 cm thick.
So, The Mat gets compressed by : 10cm - 4 cm = 6 cm=0.06 m
a)
Using Conservations of energy
Potential energy at the top = Kinetic energy at the point before touching the surface
Kinetic energy = mgh= [tex]20 \times 9.8 \times 1 = 196 J[/tex]
b)
Work done by the mat do to stop the fall of the cylinder =[tex]-mg(h+0.06)=-20 \times 9.8(1+0.06)=-208 J[/tex]
C)
Work done=[tex]\text{Average force} \times \text{ Compression of mat}[/tex]
[tex]208=F \times 0.06[/tex]
F=3467J

Answer:
-2
Step-by-step explanation:
The formula for finding the slope is y2-y1 divided by x2-x1. You can use any two points.
So,
220-240 divided by 10-0= -20/10= -2

An assembly line must create one finished product every 3 minutes. The sum of the task times required to create a product is 700 seconds. What is the theoretical minimum number of workstations for this assembly line
Answer:
We need 4 workstations configurated in series as minimum to create theoretically a finished product every 3 minutes.
Step-by-step explanation:
At first we assume that assembly line is formed solely by workstations configurated in series. We must keep in mind that theoretical minimum number of workstations is equal to the sum of the task times required to create a product divided by the time taken by the assembly line to create one finished product. That is:
[tex]n = \frac{700\,s}{3\,min\times 60\,\frac{s}{min} }[/tex]
[tex]n = 3.889\,workstations[/tex]
We need 4 workstations configurated in series as minimum to create theoretically a finished product every 3 minutes.

∠1≅∠11
vertical angles theorem
linear pair postulate
alternate interior angles theorem
alternate exterior angles theorem
corresponding angles postulate
Answer:
Correct answer is: Alternate Exterior Angles Theorem
Step-by-step explanation:
See attached picture.
The angles ∠1≅∠11 are equal by alternate exterior angles theorem and corresponding angles postulate. The correct options are A and D.
What is an alternate exterior angle?The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.
According to the alternate outside angle theorem, alternate exterior angles are regarded as congruent angles or angles of equal measure when two parallel lines are intersected by a transversal.
In the given image there are two parallel lines and one line is intersecting the two parallel lines at some angle.
Angle 1 and angle 11 will be equal to each other because of the two properties of angles that are alternate exterior angles theorem and corresponding angles postulate.
Therefore, the angles ∠1≅∠11 are equal by alternate exterior angles theorem and corresponding angles postulate. The correct options are A and D.
The image of the complete question is attached with the answer below.

D
Step-by-step explanation:
y = a[tex]x^{2}[/tex] + bx + c is an equation for a parabola in standard form.
y = a(x - h)² + k is the equation for a parabola in vertex form.
We use y = because the parabola opens vertically.
The vertex is the point on the curve of the parabola, so either the lowest or highest point depending on whether it opens up or down.
We are given the vertex of (1,3), is the vertex formula h is the x and k is the y.
(h,k) or in this case (1,3).
Let's substitute the vertex.
y = a(x - 1)² + 3
To find a, we use the other point (2,6) to substitute in x and y to solve.
x = 2 y = 6
6 = a(2 - 1)² + 3
6 = a(1)² + 3
6 = a(1) + 3
6 = a + 3 Subtract 3 from each side.
6 - 3 = a + 3 - 3
6 - 3 = a
3 = a
Now we have all the elements of the equation.
a = 3
h = 1
k = 3
y = 3(x - 1)² + 3
So the answer is D.
