Answer:

27 cm

Explanation:

ASSUMING the elevator is in a constant velocity state (could be zero)

mg = kx

x = mg/k = 15(9.8)/550 = 0.267272... m ≈ 27 cm

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 si
kotykmax [81]

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,

1N=1kg\cdot m\cdot s^{-2}

Then,

15.0N=15.0kg\cdot m\cdot s^{-2}

Converting this value to British units we have that

15N = 15.0kg\cdot m\cdot s^{-2} (\frac{1slug}{14.59kg})(\frac{1ft}{0.3048m})

15N = 3.37 slug \cdot ft \cdot s^{-2} (\frac{1 lb \cdot ft^{-1}}{1slug})

15N =3.37lb

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

What is the net force acting on a 0.15 kg hockey pick accelerating at a rate of 12 m/s
deff fn [24]
<span>According to the Newton's second law of motion F=ma, where F=force
m= Mass
a= acceleration

So F= 0.15*12
=1.8 N </span>
