Measure a pencil, end to end. Draw a sketch of the pencil and show your measurements. If you were to balance the pencil horizontally on your finger, where do you think it would be balanced? Note this on your sketch, and write down your hypothesis (distance from each end) and your prediction.
Now test your hypothesis. Balance the pencil on your finger horizontally. When it is balanced, your finger is at the center of gravity. Note and make a mark where your finger is in relation to each end of the pencil.
Measure from one end of the pencil to where your finger balanced it. Show this on your sketch, and record the data it in your chart.
Repeat steps b-c a second time for the pencil.
Repeat steps a - d using a pen and crayon as well.
What are your results? Compare your results with your hypothesis and then write an explanation in a conclusion. Which item has a center of gravity closer to the actual center that you measure?
Answer:
my pencil is about and 1/2 inches
i think it would be in the middle about 1 inch away

What is the initial velocity of a moose who
accelerates uniformly at 1.5 m/s/s for 5 seconds and
finishes with a velocity of 7 m/s?
Answer:
- 0.5 m/s
Explanation:
(1) Acceleration = change in velocity / time
(2) Change in velocity = (Final velocity - Initial velocity)
We know:
acceleration = 1.5 m/s/s
time = 5 seconds
final velocity = 7 m/s
x = initial velocity)
1.5 = ( 7 - x ) / 5
1.5 x 5 = ( 7 - x )
7.5 = 7 - x
x = -0.5 m/s
You can check the answer by plugging in the values to equation (1).
Four different blocks are resting on the floor. They each have a different mass, and they are each made of a different material, so the coefficients of friction are not the same. Using the information in the table below, rank, from highest to lowest, the magnitude of the maximum horizontal force
To answer this question, it is necessary to apply the static condition from Newton´s Laws
The solution is:
Fd > Fc > Fa > Fb
From the body free diagram, and from the second Newton´s law of movement we get:
∑ Fx = 0 F - Fr = 0 F = Fr Fr = μ×N
∑ Fy = 0 N = m×g ⇒ Therefore Fr = μ×m×g
F = μ×m×g g is the same in all the cases, then we just compare the products μ×m
So when F is just greater than Fr, the body will start moving
we make a table, with values from the information table.
1.- μ×m = 0.5× 40 = 20
2.-μ×m = 0.4× 80 = 16
3.- μ×m = 0.7× 30 = 21
4.- μ×m = 0.9× 35 = 31.5
According to the table, from highest to lowest the magnitude of the horizontal force is:
Fd > Fc > Fa > Fb

Si se impulsa un bloque con una velocidad de 15m/s sobre el piso sin rozamiento mostrado. Determinar la altura “h” que alcanzará, no existe rozamiento.
PORFAAA AYUDA URGENTE
La altura máxima alcanzada por el bloque es de 14.471 metros.
En esta pregunta asumimos que la altura inicial del bloque es igual a tres metros por encima del la altura de referencia y la altura final puede ser determinada mediante el principio de conservación de la energía, en cuyo caso, la suma de la energía cinética traslacional inicial ([tex]K[/tex]) y la energía potencial gravitacional inicial ([tex]U_{o}[/tex]), ambos en joules, es igual a la energía potencial gravitacional final ([tex]U_{f}[/tex]), en joules. Matemáticamente hablando, tenemos la siguiente expresión:
[tex]U_{o}+K = U_{f}[/tex]
[tex]m\cdot g\cdot z_{o} + \frac{1}{2}\cdot m\cdot v^{2} = m\cdot g \cdot z_{f}[/tex] (1)
Donde:
[tex]m[/tex] - Masa del bloque, en kilogramos.[tex]g[/tex] - Aceleración gravitacional, en metros por segundo al cuadrado.[tex]z_{o}[/tex], [tex]z_{f}[/tex] - Alturas inicial y final, en metros.[tex]v[/tex] - Rapidez inicial del bloque, en metros por segundo.A continuación, despejamos la altura final del bloque:
[tex]z_{f} = z_{o}+\frac{1}{2}\cdot \frac{v^{2}}{g}[/tex] (2)
Si sabemos que [tex]z_{o} = 3\,m[/tex], [tex]v = 15\,\frac{m}{s}[/tex] y [tex]g = 9.807\,\frac{m}{s^{2}}[/tex], entonces la altura máxima alcanzada por el bloque es:
[tex]z_{f} = 3\,m + \frac{1}{2}\cdot \left[\frac{\left(15\,\frac{m}{s} \right)^{2}}{9.807\,\frac{m}{s^{2}} } \right][/tex]
[tex]z_{f} = 14.471\,m[/tex]
La altura máxima alcanzada por el bloque es de 14.471 metros.

you push a block of 50kg with a force of 400 N over a distance of 8m. How much kinetic energy does the box gain?
Answer:
The box gains 3200 J of kinect energy.
Explanation:
What is kinect energy?Kinect energy is the energy of an object has because of its motion. Almost anything that has mass and it's in motion has kinect energy. Examples:
wind;throwing a footbal;driving a car;lauching a rocket;etc.What is the work energy theorem?Also known as the principle of work and kinect energy, it states that the work done by all forces acting upon an object equals the change of its kinect energy.
For example, if you pull a box, then you're exerting a force on it and it moves forward. Since the box has mass and it's in motion, you have changed its kinect energy.
Solution:
Write the data down:
[tex]\bullet \quad \mathsf{m=50\,kg}\\\\\bullet \quad \mathsf{F=400\,N}\\\\\bullet \quad \mathsf{d=8\,m}[/tex]
Apply work energy theorem:
[tex]\mathsf{W}= \Delta\mathsf{K}[/tex]
The amount work done equals the change of kinect energy:
[tex]\mathsf{W}=\mathsf{K-K_o}[/tex]
Since the block is at rest at the beginning, so it has zero initial kinect energy:
[tex]\mathsf{W}=\mathsf{K-0}\\\\\\\mathsf{W}=\mathsf{K}[/tex]
Now, apply the formula for work to the left hand side of the equation:
[tex]\mathsf{F\cdot d}=\mathsf{K}\\\\\\\mathsf{400\cdot 8}=\mathsf{K}\\\\\\\therefore \boxed{\mathsf{K=3200\,J}}[/tex]
Conclusion: the box has gained 3200 J of kinect energy.
