I HAVE 5 MINUTES!!!!!! A block oscillating on the end of a spring moves from its position of maximum spring stretch to maximum s

Verdich [7]

Therefore, if the block moves from its position of maximum spring stretch to maximum spring compression in 0.25 s, the time required for a full cycle is twice as much; T = 0.5 s.

A (B + 25.0) g mass is hung on a spring. As a result, the spring stretches (8.50 A) cm. If the object is then pulled an addition

Morgarella [4.7K]

Answer:

Time period of the osculation will be 2.1371 sec

Explanation:

We have given mass m = (B+25)

And the spring is stretched by (8.5 A )

Here A = 13 and B = 427

So mass m = 427+25 = 452 gram = 0.452 kg

Spring stretched x= 8.5×13 = 110.5 cm

As there is additional streching of spring by 3 cm

So new x = 110.5+3 = 113.5 = 1.135 m

Now we know that force is given by F = mg

And we also know that F = Kx

So $mg=Kx$

$K=\frac{mg}{x}=\frac{0.452\times 9.8}{1.135}=3.90N/m$

Now we know that $\omega =\sqrt{\frac{K}{m}}$

So $\frac{2\pi }{T} =\sqrt{\frac{K}{m}}$

$\frac{2\times 3.14 }{T} =\sqrt{\frac{3.90}{0.452}}$

$T=2.1371sec$

A 12.0-m wire with a mass of 145 g is under tension. A transverse wave, for which the frequency is 630 Hz, the wavelength is 0.5

miskamm [114]

Answer:

The maximum traverse acceleration is $\alpha = 31346.095 m/s^2$

Explanation:

Generally the maximum transverse acceleration is mathematically represented as

$\alpha = w^2 A$

Where $w$ is the angular velocity which is mathematically evaluated as

$w = 2 \pi f$

Substituting the values given in the question

$w = 2 * 3.142 * 630$

$= 3958.92 rad/s$

A is the A is amplitude with a value of 2.0mm $= \frac{2}{1000} = 0.002m$

Substituting this into the formula for maximum transverse acceleration

$\alpha = 3958.96^2 * 0.002$

$= 31346.095 m/s^2$
