# Converting m/s to Newtons

ryanking93
Homework Statement:
Add the following vectors and determine the resultants (length, angle from O)
Relevant Equations:
3 m/s. 45° + 5 m/s. 135°
So I've charted the equation above, and received the correct resultant 104.0° I used a scale of 1m/s = 2cm and I get 11.8cm which gives me 23.6m/s but when I look at the answer it is 104.0° / 5.83N

I have no idea why its in Newtons.

It is an error of the booklet, the resultant vector should be in m/s.
Note that the angle between your vectors is 90°, therefore, you could apply the Pythagorean equation and see that the result can't be 23.6 m/s.

Ahhhh I see now! My issue was when I ended up with 11.8cm instead of dividing by 2 I multiplied by 2. As my scale was 1m/s = 2cm. I end up with 5.9m/s.

Thanks a million for the help!

When adding vectors, it is good to check that the result is not greater than the addition of the magnitude of each independent vector.
You are welcome. • ryanking93
