Answer:
8.6 m/s
Explanation:
The components of the initial velocity of the ball can be found by using the equations:
where
is the horizontal component
is the vertical component
v is the magnitude of the velocity
is the angle above the horizontal
Substituting:
v = 15 m/s
We find:
The answer that would best complete the given statement above would be the term SUPERPOSITION. Here is the complete statement. <span>When two waves meet they combine according to the superposition principle. Hope this answers your question. Have a great day ahead!</span>
The false statement would be :
C. constructive interference occurs when the crest of one wave overlaps the trough of another and their individual effects are reduced or cancelled out.
Constructive interference should be when the crest of one wave overlaps another and their individual effects are add up, becoming a single wave of increased amplitude<span />
Explanation:
y = ½ at²
Multiply both sides by 2:
2y = at²
Divide both sides by a:
t² = 2y/a
Take the square root of both sides:
t = √(2y/a)
