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

vlada-n [284]

Answer:

The last one

Step-by-step explanation:

The standard method for solving an equation like 3x + 5 = 26 is to use

the Subtraction Property of Equality and then the Division Property of

Equality.

3x + 5 = 26

you would have to subtract first to get your answer

so subtract 5 on both sides

3x= 21

then u would have to divide 3 by both sides to get the x alone/ isolated

x= 7

and that is why u should use " Subtraction Property of Equality and then the Division Property of  Equality, " as your method.

Pizza-By-The-Slice sells 7 slices every 10 minutes on average. How many
Dvinal [7]
I think you’re answer is 42 slices of pizza.

the way i worked it out is by finding out how many minutes are in an hour (60 mins). after that i divided it by 10(mins), which would have gotten me 6. therefore i multiplied 7 x 6 which gave me 42.
