B.
technically it would depend if the resistors were in series or parallel but B is the answer.
Answer:
The magnitude of the acceleration is ![a_r = 1.50 \ m/s^2](https://tex.z-dn.net/?f=a_r%20%3D%201.50%20%5C%20m%2Fs%5E2)
The direction is
north of east
Explanation:
From the question we are told that
The force exerted by the wind is ![F_{sail} = (330 ) \ N \ north](https://tex.z-dn.net/?f=F_%7Bsail%7D%20%3D%20%20%28330%20%29%20%5C%20N%20%5C%20north)
The force exerted by water is ![F_{keel} = (210 ) \ N \ east](https://tex.z-dn.net/?f=F_%7Bkeel%7D%20%3D%20%20%28210%20%20%29%20%5C%20N%20%5C%20east)
The mass of the boat(+ crew) is
Now Force is mathematically represented as
![F = ma](https://tex.z-dn.net/?f=F%20%3D%20%20ma)
Now the acceleration towards the north is mathematically represented as
![a_n = \frac{F_{sail}}{m_b}](https://tex.z-dn.net/?f=a_n%20%20%3D%20%20%5Cfrac%7BF_%7Bsail%7D%7D%7Bm_b%7D)
substituting values
![a_n = \frac{330 }{260}](https://tex.z-dn.net/?f=a_n%20%20%3D%20%20%5Cfrac%7B330%20%7D%7B260%7D)
![a_n = 1.269 \ m/s^2](https://tex.z-dn.net/?f=a_n%20%20%3D%20%201.269%20%5C%20m%2Fs%5E2)
Now the acceleration towards the east is mathematically represented as
![a_e = \frac{F_{keel}}{m_b }](https://tex.z-dn.net/?f=a_e%20%3D%20%5Cfrac%7BF_%7Bkeel%7D%7D%7Bm_b%20%7D)
substituting values
![a_e = \frac{210}{260}](https://tex.z-dn.net/?f=a_e%20%3D%20%5Cfrac%7B210%7D%7B260%7D)
![a_e =0.808 \ m/s^2](https://tex.z-dn.net/?f=a_e%20%3D0.808%20%5C%20m%2Fs%5E2)
The resultant acceleration is
![a_r = \sqrt{a_e^2 + a_n^2}](https://tex.z-dn.net/?f=a_r%20%3D%20%20%5Csqrt%7Ba_e%5E2%20%2B%20a_n%5E2%7D)
substituting values
![a_r = \sqrt{(0.808)^2 + (1.269)^2}](https://tex.z-dn.net/?f=a_r%20%3D%20%20%5Csqrt%7B%280.808%29%5E2%20%2B%20%281.269%29%5E2%7D)
![a_r = 1.50 \ m/s^2](https://tex.z-dn.net/?f=a_r%20%3D%201.50%20%5C%20m%2Fs%5E2)
The direction with reference from the north is evaluated as

![tan \theta = \frac{a_e}{a_n}](https://tex.z-dn.net/?f=tan%20%5Ctheta%20%3D%20%20%5Cfrac%7Ba_e%7D%7Ba_n%7D)
![\theta = tan ^{-1} [\frac{a_e}{a_n } ]](https://tex.z-dn.net/?f=%5Ctheta%20%3D%20tan%20%5E%7B-1%7D%20%5B%5Cfrac%7Ba_e%7D%7Ba_n%20%7D%20%5D)
substituting values
![\theta = tan ^{-1} [\frac{0.808}{1.269 } ]](https://tex.z-dn.net/?f=%5Ctheta%20%3D%20tan%20%5E%7B-1%7D%20%5B%5Cfrac%7B0.808%7D%7B1.269%20%7D%20%5D)
![\theta = tan ^{-1} [0.636 ]](https://tex.z-dn.net/?f=%5Ctheta%20%3D%20tan%20%5E%7B-1%7D%20%5B0.636%20%5D)
![\theta = 32.5 6^o](https://tex.z-dn.net/?f=%5Ctheta%20%3D%20%2032.5%206%5Eo)
