Answer:

la masa de un cuerpo = 67.308 kg

Explanation:

De la pregunta, sabemos que,

magnitud de fuerza (F) = 350 N = 350 Kg / m / s^{2}

Aceleración (a)= 520 cm  / s^{2} = 5.20 m / s^{2}

A encontrar: la masa de un cuerpo (m)

Nosotras sabemos que, F = m *a

m = \frac{F}{a}

   = \frac{350 kg / m / s^{2} }{5.20 m / s^{2} }

   = 67.308 kg

Entonces, la masa de un cuerpo = 67.308 kg

An object is released from rest and falls in free fall motion. The speed v of the object after it has fallen a distance y is giv
konstantin123 [22]

Answer:

8.91 %

Explanation:

Since v² = 2gy

By the relative error formula,

2Δv/v = Δg/g + Δy/y multiplying by 100%, we have

2Δv/v × 100% = Δg/g × 100 % + Δy/y × 100%

2(Δv/v × 100%) = Δg/g × 100 % + Δy/y × 100%

Δg/g × 100 % = 2(Δv/v × 100%) - Δy/y × 100%

Since Δv/v × 100% = 3.69 % and Δy/y × 100% = 5 %

Since we have a difference for the percentage error in g, we square the percentage errors and add them together. So,

[Δg/g × 100 %]² = [2(Δv/v × 100%)]² + [Δy/y × 100%]²

[Δg/g × 100 %]² = [2(3.69)]² + [5%]²

[Δg/g × 100 %]² = [4)(3.69 %)² + [5%]²

[Δg/g × 100 %]² = 54.4644 %² + 25%²

[Δg/g × 100 %]² = 79.4644 %²

taking square-root of both sides, we have

[Δg/g × 100 %] = 8.91 %

So, the percent uncertainty in the calculated value of g is 8.91 %
