The first three steps in scientific inquiry are related in that they are all equivalent to being on a fact finding mission. The three steps are to find or develop the question that must be answered, to study all related academic literature on the subject, and then to make a guess as to what the answer is.

<h3>What is momentum?</h3>

Momentum is the product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction.

According to the question,

We define a system formed by the two balls, which are isolated and the forces during the collision are internal.

Hence , the momentum is conserved

a) The momentum of the system before the collision:

p_o = m v_1_0 + 0         p_o= 0.6 2         p_o = 1.2 kg m / s

b) The momentum of the system after the collision, as the system is isolated, the momentum is conserved so

p_f = 1.2 kg m / s

d. On X axis

p_ox = 1.2 kg m / s

p_{fx}= m v1f cos 20 + m v2f cos θ

p_o = p_f

1.2 = 0.6 (-0.8) cos 20+ 0.6v_{2f} cos θ

1.2482 =v_{2f} cos θ

e. On Y axis  

p_{oy} = 0

p_{fy}= mv_{1f}sin 20 + mv_{2f}cos θ

0 = 0.6 (-0.8) sin 20 + 0.6 v_{2f} sin θ

0.2736 =v_{2f}sin θ

Here,

g. we write our system of equations

0.2736 =v_{2f} sin θ

1.2482 = v_{2f} cos θ

0.219 = tan θ (divide)

θ = tan⁻¹ 0.21919

θ = 12.36

c. Now To find the velocity

0.2736 = v_{2f} sin θ

v_{2f}= 0.2736 / sin 12.36

v_{2f} = 1.278 m / s

Si tenemos tres cubos del mismo tamaño (hierro, madera e icopor). ¿Qué diferencias puede encontrar entre ellos?
cricket20 [7]

Answer: La diferencia es el peso (o la masa), siendo que el cubo de hierro es el mas pesado, después viene el de madera y después el de icopor.

Explanation:

Ok, los 3 cubos tienen el mismo tamaño, lo que implica que tienen el mismo volumen.

Ahora es útil recordar la relación:

Densidad = masa/volumen.

Masa = densidad*volumen.

Nosotros sabemos que la densidad del hierro es mas grande que la de la madera, y la densidad de la madera es mas grande que la del icopor.

Entonces, por la relación anterior, y sabiendo que todos los cubos tienen el mismo volumen, podemos reconocer que el cubo de hierro tiene mayor masa, después viene el de madera y después viene el de icopor.

Y sabiendo que:

masa*gravedad = peso

podemos saber que el cubo mas pesado es el de hierro, después el de madera y después el de icopor.

Además de esta diferencia, también hay otras que no dependen tanto del tamaño del objeto, como pueden ser las capacidades caloríficas, el como reaccionan a campos eléctricos y cosas así que son triviales, pues son diferentes para casi todos los materiales.
