Suppose that a car weighing 4000 pounds is supported by four shock absorbers each shock absorber has a spring constant of 6500 ibs/foot, so the effective spring constant for the system of 4 shock absorbers is 26000 lbs/foot damping and determine the period of oscillation of the vertical motion of the car. hint: g= 32 ft/sec2 1. assume no t = 0.436 seconds 2. after 10 seconds the car body is 1/3 foot above its equilibrium position and at the high point in its cycle. what were the initial conditions? ft/sec y(0) 0.317 ft. and y'(0) -1.481 x 3. now assume that oil is added to each the four shock absorbers so that, together, they produce an effective damping force of - 6.93 lb-sec/ft times the vertical velocity of the car body. find the displacement y() from equilibrium if y(0) 0 ft and _ y'(0)= -10 ft/sec y4.41e0027'sin(3.8t + t) | x

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day

which piece of furniture will have the most inertia and give the furniture movers the most difficulty in moving?  

answer

a 75kg dining table

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
