Find the value of 15.0 n in pounds. use the conversions 1slug=14.59kg and 1ft=0.3048m. express your answer in pounds to three significant figures.

The value of 15.0 N in pounds = 3.375 lb

Further explanation

The derivative magnitude is a quantity derived from the principal amount

7 main quantities have been determined based on international standards, namely:

1. Length, meters (m) 2. Time, second (s) 3. Mass, kilograms (kg) 4. Temperature, kelvin (K) 5. Light intensity, candela (cd) 6. Electric current, ampere (A) 7. Amount of substance, mol (m)

Newton (N) is one unit of force (F) which is a quantity derived from mass (m), length (l) and time (s)

Newton can be expressed in terms of Kg m / s²

Formula used:

F = m. a

N = kg. m / s²

In the British system there are units of slug, feet, and pounds so that the unit of force becomes:

F = m. a

Lb = slug. ft / s²

The relationship between the two-unit systems above is:

1 kg = 0.0685 slug

1 slug = 14.59 kg

1 newton = 0.225 lb

1 lb = 4,448 newtons

1 ft = 0.3048 m

So if we change 15 N to lb by using slug and ft

15 N = 15 * (1 / 14.59) slug * (1 / 0.3048) ft / s²

15 N = 3,375 slug ft / s ²

15 N = 3,375 lb

or we convert directly:

15 N = 15 * 0.225 lb

15 N = 3,375 lb

A vineyard has 145 acres of Chardonnay grapes

Keywords: slug, Newton, feet, kg, pound

15 N = 15  kg m / s² = 
= 15 · 1/14.59  slug · 1 / 0.3048 =
= 15 · 0.06854 · 3.24254 = 
= 3.33 lb
 15 N is equal to 3.33 pounds.

Given the equivalent value to convert the units from kilograms to slug and feet to meters, we will proceed to define the equivalence of the 'Newton' in simplified units, that is,

Then,

Converting this value to British units we have that

Therefore the value of 15.0 N in pounds is 3.37 lb.
