Answer:
<em>When a ball is thrown up acceleration is same throughout </em><em>the journey and velocity is zero at its maximum height.
</em>
Explanation:
The movement of a ball thrown up is completely under the influence of gravity. Thus the only acceleration it can have is the acceleration due to gravity 
. Hence, at every point in the upward and downward journey its acceleration will be equal to g.
At the maximum height the velocity of the ball will be zero since it is momentarily at rest.
Answer:
We can easily find out the beginning point of the line by using dot representation.
Explanation: When it comes to position vector, it expresses the exact position of certain object from the starting point of the coordinate system. The vector is a straight line that has a certain end which is fixed to its body.

Answer:
- Fx = -9.15 N
- Fy = 1.72 N
- F∠γ ≈ 9.31∠-10.6°
Explanation:
You apparently want the sum of forces ...
F = 8.80∠-56° +7.00∠52.8°
Your angle reference is a bit unconventional, so we'll compute the components of the forces as ...
f∠α = (-f·cos(α), -f·sin(α))
This way, the 2nd quadrant angle that has a negative angle measure will have a positive y component.
= -8.80(cos(-56°), sin(-56°)) -7.00(cos(52.8°), sin(52.8°))
≈ (-4.92090, 7.29553) +(-4.23219, -5.57571)
≈ (-9.15309, 1.71982)
The resultant component forces are ...
Then the magnitude and direction of the resultant are
F∠γ = (√(9.15309² +1.71982²))∠arctan(-1.71982/9.15309)
F∠γ ≈ 9.31∠-10.6°
Answer:
Electronic Health Record (EHR)
Explanation:
An Electronic Health Record is basically a digital equivalent of a patient's medical record. They are extremely useful because they provide a concise and accurate history of all of the patient's former treatments, exams and ilnesses, which help in optimization of the treatment process by eliminating extra steps like retaking exams and reducing the odds of medical errors.
