Answer: The answer is letter H
Answer:
Explanation:
Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.
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:
![\displaystyle \tan\theta=\frac{\text{opposite leg}}{\text{adjacent leg}}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Ctan%5Ctheta%3D%5Cfrac%7B%5Ctext%7Bopposite%20leg%7D%7D%7B%5Ctext%7Badjacent%20leg%7D%7D)
The opposite leg to θ is 4 and the adjacent leg is 8, thus:
![\displaystyle \tan\theta=\frac{4}{8}=\frac{1}{2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Ctan%5Ctheta%3D%5Cfrac%7B4%7D%7B8%7D%3D%5Cfrac%7B1%7D%7B2%7D)
Calculating the angle:
![\displaystyle \theta=\arctan\left(\frac{1}{2}\right)](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Ctheta%3D%5Carctan%5Cleft%28%5Cfrac%7B1%7D%7B2%7D%5Cright%29)
![\theta\approx 26.6^\circ](https://tex.z-dn.net/?f=%5Ctheta%5Capprox%2026.6%5E%5Ccirc)
Thus the required angle is 90° + 26.6° = 116.6°
The angle between vectors A and B is 116.6°.
