The displacement d (in meters) of an object at time t (in seconds) is given.
d= sin(t/9)
(a) Describe the motion of the object.
is it simple harmonic motion or damped motion?
(b) What is the maximum displacement from its resting position? Round your answer to two decimal places.
in meters
(c) What is the time required for one oscillation? Round your answer to two decimal places.
in seconds
(d) What is the frequency? Round your answer to two decimal places.
in oscillation/second

Best ResponseYou've already chosen the best response.0simple harmonic i believe; there is no part of it that is accounting for a dampned effect

Best ResponseYou've already chosen the best response.0the displacement from rest is the amplitude; which is 1 the initial displacement tho is 1

Best ResponseYou've already chosen the best response.0well.... yeah, initial = 0 :)

Best ResponseYou've already chosen the best response.01/18pi is the frequency

Best ResponseYou've already chosen the best response.0and hence18pi is the time period for one oscillation

Best ResponseYou've already chosen the best response.0so max disp is 0 or 1?

amistre64

Best ResponseYou've already chosen the best response.0are you accounting for the pi already in the problem? or are you atributing an external pi?

Best ResponseYou've already chosen the best response.0see the eqn for shm is x=sin (wt)

anonymous

Best ResponseYou've already chosen the best response.0w=1/9 hence f = 1/18pi

Best ResponseYou've already chosen the best response.0i get turned around whe w = pi/n lol

Best ResponseYou've already chosen the best response.0and since T=1/f , T=18pi

Best ResponseYou've already chosen the best response.0i did it before but forgot. is it got to do with the pendulums?

anonymous

Best ResponseYou've already chosen the best response.0yeah...anything in shm follows the displacement eqn x = Asin(wt) w is called the angular frequency and equals 2pi x f where f is the frequency

Best ResponseYou've already chosen the best response.0and f=1/T where T is the time for one cycle or oscillation

Best ResponseYou've already chosen the best response.0max disp from its resting position isnt 1 tho

anonymous

Best ResponseYou've already chosen the best response.0im not sure. but the answer u got is 1.00? its not right for some reason

anonymous

Best ResponseYou've already chosen the best response.0it must be to two dp and be in meters

anonymous

Best ResponseYou've already chosen the best response.0gotta be 1.00...dunno y its coming out wrong..

Best ResponseYou've already chosen the best response.0me either but it aint working. tried it already

Best ResponseYou've already chosen the best response.0how do u work that part anyways?

anonymous

Best ResponseYou've already chosen the best response.0hey amistre, the max disp from rest is turnin out wrong

anonymous

Best ResponseYou've already chosen the best response.0i put in 1.00 and 1.00 both r wrong

amistre64

Best ResponseYou've already chosen the best response.0thats becasue we assumed displacement = amplitude d = displacement; so we gotta work the formula :)

anonymous

Best ResponseYou've already chosen the best response.0amplitude is defined as the max displacemnt from the mean position

amistre64

Best ResponseYou've already chosen the best response.0it peaks at +1 it aint asking for the value of 't' at the max becasue there aint no interval to associate a single t into

amistre64

Best ResponseYou've already chosen the best response.0have you tried it without the decimals?
