Problem
The displacement of a point on a string is given by
y
(
x
,
t
)
=
3.0
sin
(
0.80
x
−
30
t
)
mm
y(x,t)=3.0\,\sin\,(0.80\,x-30\,t)\,\text{mm}
y
(
x
,
t
)
=
3.0
sin
(
0.80
x
−
30
t
)
mm
, where
x
x
x
is in metres and
t
t
t
in seconds. For the particle located at
x
=
0
x=0
x
=
0
, determine the earliest time after
t
=
0
t=0
t
=
0
when its velocity becomes zero again.
