A weight attached to a spring is at its lowest point, 9 inches below equilibrium, at time t = 0 seconds. When the weight it rele
a_sh-v [17]
The motion can be modeled as
x(t) =9 \, cos( \frac{2 \pi t}{T} )
where 
x = the position below the equilibrium position
T =  the period of the motion
t = time

The weight returns to its equilibrium position when x = 0. 
This occurs when
\frac{2 \pi t}{T} = \frac{ \pi }{2}
That is,
t= \frac{T}{4}

Because the weight returns to the equilibrium position when t =  3 s, therefore
T = 12 s
The motion is
x(t) = 9 \, cos( \frac{ \pi t}{6} )

When t = 1 s, the position of the weight from equilibrium is
d = 9 \, cos( \frac{ \pi }{6} ) = 9( \frac{1}{2} ) = 4.5 \, in

Answer:
d = 9 \, cos( \frac{ \pi }{6} ) = 4.5 \, in

Jackie’s test scores for the first semester are listed below.
jek_recluse [69]

Answer:

The answer is 91

Step-by-step explanation:

90 x 6 = 540

The numbers need to equal 540 all together to make an average of 90.

97 + 86 + 83 + 95 + 88 = 449

540 - 449 = 91

To check:

97 + 86 + 83 + 95 + 88 + 91 = 540

Therefore, the answer is 91
