Answer:
Explanation:
3.4 m/s due North, -1.1 m/s due East
Answer:
c. 60 feet is the correct answer
Explanation:
what is the contour interval of this map? a.20 b.-20 c. 60 feet 11
If the velocity of the train is v=s/t, where s is the distance and t is time, then v=400/5=80m/s. To get the vertical component of the velocity we need to multiply the velocity v with a sin(α): Vv=v*sin(α), where Vv is the vertical component of the velocity and α is the angle with the horizontal. So:
Vv=80*sin(10)=80*0.1736=13.888 m/s.
So the vertical component of the velocity of the train is Vv=13.888 m/s.
