If an object on a horizontal frictionless surface is attached to a spring, displaced, and then released, it will oscillate. It i

Kaylis [27]

Answer:

a.0.120mm

b.1.58s

c.0.6329Hz

Explanation:

a. Given that 0.120mm is displaced from equilibrium, 0.120mm after 0.790s on opposite side:

-The amplitude is the maximum displacement from equilibrium.

-The object goes from x=+A to x=-A and back during one cycle.

#Hence, the amplitude of the motion is 0.120mm

b.Motion from maximum positive displacement to maximum negative displacement takes places during half the period of Simple Harmonic Motion(SHM)

$0.790s=T/2\\\\T=0.790s\times 2\\\\T=1.58s$

#Hence, the period of the motion is 1.58s

c. Frequency is calculated as one divided by the period of the motion.

From b above we know that the motions period is 1.58s

Therefore:

Frequency=1/period=1/1.58=0.6329Hz

#The frequency of the motion is 0.6329Hz

A particle hangs from a spring and oscillates with a period of 0.2s.If the mass-spring system remained at rest, by how much woul

Answer:

The distance the mass would stretch it is $x = 0.00992948$

The correct option is A

Explanation:

From the question we are told that

The period of the slit is $T = 0.2s$

The acceleration due to gravity is $g =9.8 m/s^2$

Generally the period is mathematically represented as

$T = 2 \pi \sqrt{\frac{m}{k} }$

Whee m is the particle and k is the spring constant

making $\frac{m}{k}$ the subject

$\frac{m}{k} = [\frac{T}{2 \pi} ]^2$

The weight on the particle is related to the force stretching the spring by this mathematical relation

$W = F_s$

$mg = kx$

where x is the length by which the spring is stretched

$\frac{m}{k} = \frac{x}{g}$

Substituting the equation above for $\frac{m}{k}$

$[\frac{T}{2 \pi} ]^2 = \frac{x}{g}$

making x the subject

$x = g [\frac{T}{2 \pi} ]$

Substituting the value

$x = 9.8 * [\frac{0.2}{2 * 3.142} ]^2$

$x = 0.00992948$

Complete the statement below with all that apply.

lianna [129]

Acceleration is the rate of change of velocity, and velocity is the change in displacement over the change in time so the answer would be A.
