A mass weighting 64 pounds, attached to the end of a spring and stretches the spring 0.32 foot. There is no damping and no exter

nal forces acting on the system. The mass is initially released from a point 8 inches above the equilibrium position with a downward velocity of 5 ft/s.
a) Find the displacement at any time t, ut) (find the equation of motion)

b) What are the amplitude and period of motion?

c) How many complete cycles will the mass have completed at the end of 37 seconds?

d) At what time does the mass pass through the equilibrium position heading downward at the second time?

e) At what times does the mass attain its extreme displacements on either side of the equilibrium position?

f) What is the position of the mass at t-3 sec?

g) What is the instantaneous velocity at t-3 sec?

h) What is the acceleration at t=3sec?

i) What is the instantaneous velocity at the time when the mass passes through the equilibrium position?

j) At what time is the mass 5 inches below the equilibrium position?

k) At what time is the mass 5 inches below the equilibrium position heading in the upward direction?

PLEASEE HELP.!! ILL GIVE BRAINLIEST.!! *EXTRA POINTS* DONT SKIP:((
shtirl [24]

♡ The Question ♡

- Order the following numbers from least to greatest. Put the lowest number on the left. -25, 33, 59, -62

*୨୧ ┈┈┈┈┈┈┈┈┈┈┈┈ ୨୧*

♡ The Answer ♡

-  -62, -25, 33, 59 <--- Least to Greatest

*୨୧ ┈┈┈┈┈┈┈┈┈┈┈┈ ୨୧*

♡ The Explanation/Step-By-Step ♡

- These numbers can be represented on a number line from negative numbers, to 0, to whole numbers! So the lowest numbers will be our negative numbers, then our greatest will be the whole numbers. The higher amount the number such as -62, the more farther away it is on the number line making this our LOWEST NUMBER. 59 is the highest positive number making this our HIGHEST NUMBER. Whole numbers are greater than negative numbers so we can safely assume -25 goes before 33, so our results should be: -62, -25, 33, 59!

*୨୧ ┈┈┈┈┈┈┈┈┈┈┈┈ ୨୧*

♡ Tips ♡

- Try to use a number line, if you need anymore help feel free to look up videos on how to do this or ask the questions on Brainly! Hope this helped!

ehidna [41]

Answer:

the horizontal position for the left edge of the image is -4.46 cm.

Step-by-step explanation:

The horizontal midpoint of the page is:

21.59 / 2 = 10.79 cm

The horizontal midpoint of the image is given as:

30.51 / 2 = 15.25 cm

These midpoints must be on the same point in the axis.

By taking the leftmost edge of the paper to be point zero on the axis, then, the distance accommodated by the paper is 10.795 cm.  

The distance that goes beyond this leftmost edge is computed as;

This is on the negative side on the axis.

Thus the horizontal position for the left edge of the image is -4.46 cm.
