Answer:
Vs/c = 20 [m/s]
Explanation:
This is a problem of relative velocities, as velocity is a vector we can use addition or subtraction of vectors for the solution.
We are asked for the velocity of the sailboat with respect to an observer located in the canoe.
![V_{s/c}=V_{sailboat}-V_{canoe}\\V_{s/c}=15-(-5)\\V_{s/c}=20[m/s]](https://tex.z-dn.net/?f=V_%7Bs%2Fc%7D%3DV_%7Bsailboat%7D-V_%7Bcanoe%7D%5C%5CV_%7Bs%2Fc%7D%3D15-%28-5%29%5C%5CV_%7Bs%2Fc%7D%3D20%5Bm%2Fs%5D)
Why is the speed of the canoe negative?, it is negative because the canoe moves in the opposite direction to the sailboat.
the Doppler effect. (I don't know how to explain it lol)
B. Electrons are negative so one single 1 would be negative 1
