upward

B.
toward the right

C.
toward the left

D.
downward
Based on the data given, in what direction will the - 1

Answers

Answer 1
Answer: Vertical forces:
There is a force of 579N acting upward, and a force of 579N
acting downward.
The vertical forces are balanced ... they add up to zero ...
so there's no vertical acceleration. 
Not up, not down.

Horizontal forces:
There is a force of 487N acting to the left, and a force of 632N
acting to the right.
The net horizontal force is

        (487-left + 632-right)  -  (632-right - 487-right) =  145N to the right.

The net force on the car is all to the right.
The car accelerates to the right.

The displacement vector from your house to the library is 520 m long, pointing 40 ∘ north of east.What are the x-component (x-axis is directed from west to east) of this displacement vector?What are the y-component (y-axis is directed from south to north) of this displacement vector?

Answers

Answer:

398.3 m, 334.2 m

Explanation:

The magnitude of the displacement vector is

v = 520 m

And its direction is

\theta=40^(\circ)

measured as north of east.

The x-component of this vector is given by:

v_x = v_0 cos \theta = (520)cos 40^(\circ)=398.3 m

While the y-component is given by

v_y = v_0 sin \theta =(520)sin 40^(\circ)=334.2 m

Final answer:

The x-component of the displacement vector (east-west direction) is approximately 398 m and the y-component (north-south direction) is approximately 334 m.

Explanation:

Displacement vectors contain both magnitude and direction information. In the case of a displacement vector 520 m long, pointing 40 degrees North of East, we can break it down into x and y components using trigonometric functions, specifically cosine and sine.

For the x-component (east-west direction), we can use the cosine function because it gives us the adjacent side in a right triangle, which is the east-west direction in our case. Therefore, the x-component will be:
520 m * cos(40) = 398m (rounded to nearest unit).

For the y-component (north-south direction), we can use the sine function because it gives us the opposite side in a right triangle, which is the north-south direction in our case. Hence the y-component will be:
520 m * sin(40) = 334 m (rounded to nearest unit).

How does acceleration affect velocity

Answers

you get a repetative increase in velocity 
Well the rate at which velocity changes with time is called Acceleration. Accelerating is a measure of how quickly the velocity is changing. If velocity doesn't change, there is no acceleration. 

In one sentence, explain the relationship between velocity, speed, and acceleration

Answers

Velocity consists of speed and direction combined, while speed is just the rate of movement, and acceleration is the change in velocity over time
