The equation of motion of a block with mass m = 8 kg. attached to a spring whose spring Constant is k = 2 and which starts from
Annette [7]

Answer:

FALSE

Step-by-step explanation:

In order to be consistent with the system of unit we should decide if we are going to work with the CGS system <em>(centimeter-gram-second)</em> or the MKS system <em>(meter-kilogram-second). </em>

If we decide to work with the CGS system, the equation of motion would be

8,000x ′′ + 2x = 0; x(0) = 3, x ′ (0) = 0

since 1 Kg = 1,000 g

If we decide to work with the MKS system, the equation of motion would be

8x ′′ + 2x = 0; x(0) = 0.03, x ′ (0) = 0

given that 1 mt = 100 cm

I need help in area it's hard
Fofino [41]
The area is the length times the width. Find area of shapes by counting unit squares. Some shapes will require combining partial square units to find area.<span>  

        For example - </span><span>A rectangle is 5 centimeters long and 4 centimeters wide. What is its area? </span>

Area = Length * width  

The length is <span><span>5</span></span> centimeters. The width is <span><span>4</span></span> centimeters. So the area is <span><span>5 times </span>4</span> square centimeters.

= 20 square centimeters

5x-2y=30 complete the missing value in the solution to the question (8, )
natali 33 [55]

Answer:

(8,5)

Step-by-step explanation:

5x-2y=30

lets substitute "8" as x and see where that takes us

5(8)-2y=30

40-2y=30

subtract 40 on both sides

-2y=-10

divide by "-2" on both sides

y=5

(8,5) is your answer
