The relationship between linear velocity and angular velocity
bonufazy [111]

In linear motion , when a body moves with uniform velocity , in time t , its linear displacement will be ;

S = r∅     S = vt

r∅ =  vt

r.∅ / t = v

As

v = rw

where ∅ = 90° is the angle between between radius vector r  and angular velocity w (omega )

In case ∅ ≠ 90° , we can write v = r w sin∅

It gives us v = w× r

What is the speed v of a wave traveling down such a wire if the wire is stretched to its breaking point?
Ilya [14]

Answer:

v = 620.17 m/s

Explanation:

There are different formulas for calculating the speed of a wave. Based on the given parameters, the speed of the wave can be estimated as:

v = sqrt(breaking tensile strength/density)

Where:

The breaking tensile strength = 3*10^9 N/m^2

Density = 7800 kg/m^3

Therefore, we can estimate the speed of the wave as shown below:

v = sqrt(3*10^9/7800) = sqrt(384615.3846) = 620.17 m/s
