A rotating beacon is located 2 miles out in the water. Let A be the point on the shore that is closest to the beacon. As the bea

Answer:

$v = 3369.2 m/s$

Explanation:

The beacon is rotating at an angular speed of

$f = 10 rev/min$

so we have

$\omega = 2\pi f$

$\omega = 2\pi(\frac{10}{60})$

$\omega = 1.047 rad/s$

We know that

$v = r \omega$

At this point we have

$r = 2 miles = 2(1609 m)$

$r = 3218 m$

So we can conclude with

$v = 3218(1.047)$

$v = 3369.2 m/s$

What mass needs to be attached to a spring with a force constant of 7N/m in order to make a simple harmonic oscillator oscillate

Sav [3153]

Answer:

The mass will be 4.437 kg

Explanation:

The force constant k is given as 7 N/m

The time period of oscillation T is 5 sec

Thus, angular frequency $\omega =\frac{2\pi }{T}=\frac{2\times 3.14}{5}=1.256rad/sec$

It is known that angular frequency is computed via

$\omega =\sqrt{\frac{k}{m}}$

$1.256 =\sqrt{\frac{7}{m}}$

Squaring both sides gives us

$1.577 =\frac{7}{m}$

The mass equals 4.437 kg
