The world's largest pendulum clock has a period of 2.00 seconds with a maximum amplitude of
0.345 m to either side of the equilibrium position (EQ). [4]
a. Find a possible equation for the displacement of the spring from EQ at t seconds.

The displacement equation for this periodic motion is given as

y = (0.345 Sin πt) m

y = (0.345 Sin 3.142t) m

Step-by-step explanation:

The displacement equation for periodic motion is given as

y = A sin wt

A = amplitude of the motion, that is, the maximum displacement from the equilibrium position = 0.345 m

w = angular frequency = (2π/T)

T = period of the periodic motion = 2.00 s

w = (2π/T) = (2π/2) = π rad/s

t = time of motion, measured in seconds.

y = (0.345 Sin πt) m

y = (0.345 Sin 3.142t) m

Hope this Helps!!!

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
