Impulse describes the change of momentum. Since we don't know the momentum of the soccer ball before the hit, this question is hard to answer. If you assume the momentum of the ball before the hit was p = 0, then the change in momentum is just Δp = Impulse = mv.
Answer:
B) 4500 Pa
Explanation:
As pressure is force per unit area,
P = F/A
It stands to reason that the smallest pressure for a given force is when it is shared by the largest area.
The possible areas are
0.30(0.40) = 0.12 m²
0.30(0.50) = 0.15 m²
0.40(0.50) = 0.20 m²
The pressure when the face with the largest area (0.20 m²) is down is
P = 900 / 0.20 = 4500 N/m² or 4500 Pa
the other possible pressures would be
900/0.15 = 6000 Pa
900/0.12 = 7500 Pa
which are both larger than our solution.
You could do something about Einstein's theory of energy... it seems like it would be a simple and easy project. E=mc^2
The answer is kinetic energy
The resulting wave will have zero amplitude, thus it will form a straight line.
<h3>What is a crest?</h3>
A crest is an upward displacement of a progressive wave.
<h3>What is a trough?</h3>
A trough is a downward displacement of a progressive wave.
<h3>Superimposition of the two waves</h3>
When the two waves meet each other at point X, they will superimpose and cancel out since they have equal amplitude and are in opposite direction.
The resulting wave will have zero amplitude, thus it will form a straight line.
