A 30.0-kg box is being pulled across a carpeted floor by a horizontal force of 230 N , against a friction force of 210 N . What

olga2289 [7]

Answer:

0.67 m/s² or 2/3 m/s²

3 m

Explanation:

Using

F-F' = ma............ Equation 1

Where F = Horizontal force applied to the box, F' = Frictional force, m = mass of the box, a = acceleration of the box.

make a the subject of the equation

a = (F-F')/m............ Equation 2

Given: F = 230 N, F' = 210 N, m = 30 kg.

substitute into equation 2

a = (230-210)/30

a = 20/30

a = 0.67 m/s² or 2/3 m/s²

The acceleration of the box = 2/3 m/s²

Using,

s = ut+1/2at²............ Equation 3

Where u = initial velocity, t = time, a = acceleration, s = distance.

Given: u = 0 m/s (from rest), t = 3 s, a = 2/3 m/s²

substitute into equation 3

s = 0(3)+1/2(2/3)(3²)

s = 3 m.

Hence the box moves 3 m

Which statement is an example of determining the relative age?

const2013 [10]

knowing the age of a grandmother because she was a kid during the Great Depression

Explanation:

The best example for relative age is simply knowing the age of a grandmother because she was a kid during the Great Depression. Relative age is usually based on the occurrence of a popular and world wide event. It is not an absolute age that gives numerical and quantitative values to age.

The reference here is the Great Depression
The Grandmother was kid during this period in time.
We can use this knowledge to infer her age.
Since she was a kid at that point, her current age would how far back the depression was and an estimate of her age at that time.
