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.
Answer:
s=1721.344m ,v=104.96m/s.
Explanation:
using thr equation of motion;

u=0, plane starts from rest,


s=1721.344m
v=u+at
v=0 +3.2*32.8
v=104.96m/s
