a 2.00 kg friction-less block is attached to an ideal spring with force constant 315 N/m.Initially, the spring is neither stretc
Setler [38]

Answer

given,

mass of block, m = 2 Kg

spring constant, k = 315 N/m

speed of the block, v = 12 m/s

a) Amplitude of the motion

   A = v \sqrt{\dfrac{k}{m}}

   A =\dfrac{12}{\sqrt{\dfrac{315}{2}}}

         A = 0.956 m

b) maximum acceleration of the block

    a_{max}= A \dfrac{k}{m}

    a_{max}= 0.956\times \dfrac{315}{2}

    a_{max}= 150.57\ m/s^2

c) maximum Force

  F_{max} = m a_{max}

  F_{max} = 2\times 150.57

  F_{max} = 301.14\ N

Two exactly similar wire of steel and copper are stretched by equal force.if the total elongation is 10cm.find how much each wir
antiseptic1488 [7]

Answer:

The copper wire stretches 6.25 cm and the steel wire stretches 3.75 cm.

Explanation:

Young's modulus is defined as:

E = stress / strain

E = (F / A) / (dL / L)

E = (F L) / (A dL)

Solving for dL:

dL = (F L) / (A E)

The wires have the same force, length, and cross-sectional area.  So:

dL₁ + dL₂ = (FL/A) (1/E₁ + 1/E₂)

Given that dL₁ + dL₂ = 0.10 m, E₁ = 20×10¹⁰ N/m², and E₂ = 12×10¹⁰ N/m²:

0.10 = (FL/A) (1/(20×10¹⁰) + 1/(12×10¹⁰))

FL/A = 0.75×10¹⁰ N/m

Solving for dL₁ and dL₂:

dL₁ = (FL/A) / E₁

dL₁ = (0.75×10¹⁰ N/m) / (20×10¹⁰ N/m²)

dL₁ = 0.0375 m

dL₂ = (FL/A) / E₂

dL₂ = (0.75×10¹⁰ N/m) / (12×10¹⁰ N/m²)

dL₂ = 0.0625 m

The copper wire stretches 6.25 cm and the steel wire stretches 3.75 cm.
