Answer:
Mass, m = 0.49 kg
Explanation:
It is given that,
A block of ice is sliding down a ramp of slope 45° to the horizontal. At the bottom of the ramp, the block strikes a wall with a force of 3.4 N.
We need to find the mass of the ice.
On a sloping surface, the force with which it strikes is given by :
So, the mass of the ice block is 0.49 kg.

Answer:
- Yes.
Explanation:
A particular solution for the 1D wave equation has the form
where A its the amplitude, k the wavenumber, ω the angular frequency and φ the phase angle.
Now, for any given position , we can use:
so, the equation its:
.
This is the equation for a simple harmonic oscillation!
So, for any given point, we can use a simple harmonic oscillation as visual model. Now, when we move a distance from the original position, we got:
and
now, this its
So, there its a phase angle difference of . We can model this simply by starting the simple harmonic oscillation with a different phase angle.
