Answer: 50m/s
Explanation: if you add 10 x 1 is 10 so you leave it as 10 then you do 10 x 5 which will come out as 50 so then you get the answer 50m/s

Answer:
<em>The angle between vectors A and B is 116.6°.</em>
Explanation:
<u>Geometric Addition of Vectors</u>
The geometric construction of the situation stated in the question is shown in the image below.
The angle between vectors A and B is the sum of 90° and θ.
Angle θ can be found by working on the right triangle of side lengths 8 and 4, and angle θ.
We use the tangent ratio:
The opposite leg to θ is 4 and the adjacent leg is 8, thus:
Calculating the angle:
Thus the required angle is 90° + 26.6° = 116.6°
The angle between vectors A and B is 116.6°.
