Answer/Step-by-step explanation:
Recall the acronym for trigonometric ratios: SOHCAHTOA
SOH means sine of the reference angle = opp/hypotenuse
CAH means cosine of the reference angle = Adj/hyp
TOA means tangent of the reference angle = opp/adj
a. Reference angle = A
opp = 15
hypotenuse = 17
Therefore:
b. Reference angle = A
Adj = 8
hypotenuse = 17
Therefore:
c. Reference angle = A
Adj = 8
Opp = 15
Therefore:
d. Reference angle = B
Opp = 8
hypotenuse = 17
Therefore:
e. Reference angle = B
Adj = 15
hypotenuse = 17
Therefore:
d. Reference angle = B
Opp = 8
Adj = 15
Therefore:
If you multiply by three twice, you're multiplying by six once
Answer:
v (E) = √(2E/m)
Step-by-step explanation:
From the question given:
E = ½mv²
E is the kinetic energy
m is the mass of object
v is the velocity.
To find a model v(E) for the velocity of the object, we simply make V the subject of the above equation.
This can be obtained as follow:
E = ½mv²
Cross multiply
mv² = 2E
Divide both side by m
v² = 2E/m
Take the square root of both side
v = √(2E/m)
Therefore, the model v(E) for the velocity of the object is given by:
v (E) = √(2E/m)
