The wave is equation with the given conditions is y = 0.02 cos ( 0 )
<u>Given data</u>
period T= 25.0ms
speed of 30.0 m/s
t = 0
x = 0
transverse position of 2.00cm
speed of 2.0 m/s = v
<h3>writing the wave function </h3>
frequency f = 1 / T
f = 1 / 25
f = 0.04Hz
Angular velocity = ω = 2 * pi * f
ω = 2 * pi * 0.04
ω = 0.251
wave number K = ω / v
k = 0.251 / 2
k = 0.126
The wave equation
y = A cos ( kx + ωt )
this is equivalent to
y = 0.02 cos ( 0.126 * 0 + 0.251 * 0 )
y = 0.02 cos ( 0 )

Thermal energy is an example of kinetic energy<span>, as it is due to the motion of particles, with motion being the key. Thermal energy results in an object or a system having a temperature that can be measured. Thermal energy can be transferred from one object or system to another in the form of heat.</span>
Initial velocity of the object: 5 m/s
Explanation:
The figure in the problem is missing: find it in attachment.
The graph in the figure represents the velocity of an object (v) versus the time passed (t).
Here we are asked to find the initial velocity of the object.
This means that we have to find the velocity of the object when the time is zero, so when
t = 0
By looking at the corresponding value on the y-axis (velocity), we see that when t = 0, then
v = 5 m/s
Therefore, the initial velocity of the object is 5 m/s.
