Answer:
10 cos (30)N
Explanation:
So, if we were to visualize it for a sec
we would see 10 as the hypotenuse, 30 as the angle between and would be solving for the adjacent side
So, using basic trig rules,
using the fact that cos(30)=x/10
x=10 cos (30)N
Displacement will be zero.
<h3>What is displacement and how is it different from distance?</h3>
Displacement:
- It is the shortest distance between an object's beginning position and ending position.
- The quantity is a vector.
- It may be zero, positive, or negative.
- Displacement may be greater than or equal to distance.
In the given question, we start from one point and finish at the same point around the circular track. Therefore there is no distance between the initial and final points because they are the same. That's why the displacement is zero.
Distance:
- It is the actual path or distance that an object takes to go from its starting point to its finishing point.
- The quantity is a scalar one.
- It cannot be 0 or negative; it must be positive.
- Displacement and distance may be equal.

The answer of speed is 4.5m/s
Answer:
Vx = 35.31 [km/h]
Vy = 18.77 [km/h]
Explanation:
In order to solve this problem, we must decompose the velocity component by means of the angle of 28° using the cosine function of the angle.
![v_{x} = 40*cos(28)\\V_{x} = 35.31 [km/h]](https://tex.z-dn.net/?f=v_%7Bx%7D%20%3D%2040%2Acos%2828%29%5C%5CV_%7Bx%7D%20%3D%2035.31%20%5Bkm%2Fh%5D)
In order to find the vertical component, we must use the sine function of the angle.
![V_{y}=40*sin(28)\\V_{y} = 18.77 [km/h]](https://tex.z-dn.net/?f=V_%7By%7D%3D40%2Asin%2828%29%5C%5CV_%7By%7D%20%3D%2018.77%20%5Bkm%2Fh%5D)
