Answer:
0.72
Step-by-step explanation:
Answer: 12
Step-by-step explanation:
law of cosines states that f^2 = t^2 + p^2 - 2tp cos(F)
so f^2 = 5^2 + 7^2 - 2*5*7*cos(175)
f^2 = 74 - (-69.7336)
f^2 = 143.7336
f = 11.9889
which rounds to 12
Answer:
235.54 N
Step-by-step explanation:
Since this is an addition of vectors, we need to find the components of each in the x-y plane. Given that the first vector (100 N) is along the x axis, it consist of just x component of size: 100N.
For the second vector, its x-component will be given by the cosine projection on the x axis via:
x-component
and its y-component will be given by the "sine" projection:
y component
Therefore the addition of the x-components for the final vector is:
100N + 114.9N = 214.9 N
Now we use the Pythagorean theorem to find the magnitude of the resultant addition of vectors:
I know for sure it's rational and an integer. I don't think there should be anymore to apply.
