Answer:

Explanation:
Recall the formula for acceleration:
 , where
, where  is final velocity,
 is final velocity,  is initial velocity, and
 is initial velocity, and  is elapsed time (change in velocity over this amount of time).
 is elapsed time (change in velocity over this amount of time).
Let's look at our time vs velocity graph. At t=0 seconds, V=25 m/s. So her initial velocity is 25 m/s.
We want to find the acceleration during the first 5 seconds of motion. Well, looking at our graph, at t=5 seconds, isn't our velocity still 25 m/s? Therefore, final velocity is 25 m/s (for this period of 5 seconds).
We are only looking from t=0 seconds to t=5 seconds which is a total period of 5 seconds. Therefore, elapsed time is 5 seconds.
Substituting values in our formula, we have:

Alternative:
Without even worrying about plugging in numbers, let's think about what acceleration actually is! Acceleration is the change in velocity over a certain period of time. If we are not changing our velocity at all, we aren't accelerating! In the graph, we can see that we have a straight line from t=0 seconds to t=5 seconds, the interval we are worried about. This indicates that our velocity is staying the same! At t=0 seconds, we have a velocity of 25 m/s and that velocity stays the same until t=5 seconds. Even though we are moving, we haven't changed velocity, which means our average acceleration is zero!
 
        
             
        
        
        
Milk, apples, and beans don't have much carbohydrate.  So if you 
cut down on those, you don't really cut down much on carbohydrates.
If Rachel needs to reduce her intake of carbohydrates, she should 
cut down on bread.  (Also cake, sugar, corn, pasta, and potatoes.)
        
             
        
        
        
Answer:
57 N
Explanation:
Were are told that the force
of gravity on Tomas is 57 N.
And it acts at an inclined angle of 65°
Thus;
The vertical component of the velocity is; F_y = 57 sin 65
While the horizontal component is;
F_x = 57 cos 65
Thus;
F_y = 51.66 N
F_x = 24.09 N
The net force will be;
F_net = √((F_y)² + (F_x)²)
F_net = √(51.66² + 24.09²)
F_net = √3249.0837
F_net = 57 N
 
        
             
        
        
        
Colors seen on the cover of our physics book result from color is due to Subtraction.
What is physics of color subtraction?
- Some visible spectrum wavelengths are intentionally removed during the subtraction procedure. 
- For instance, the yellow filter transmits the green and red colors while blocking the blue. 
- Red and blue are transmitted while the green is blocked by the magenta filter. 
- Blue and green are transmitted while red is blocked by the cyan filter. 
- Subtractive mixing gets its name from the fact that when colors are mixed, wavelengths are removed from what we see because each paint absorbs some of the wavelengths that the other paint reflects, leaving us with less wavelengths afterward.
