Answer:

La densidad (más precisamente, la densidad de masa volumétrica; también conocida como masa específica), de una sustancia es su masa por unidad de volumen. El símbolo más utilizado para la densidad es la letra griega en minúsculas rho), aunque también se puede utilizar la letra latina D. Matemáticamente, la densidad se define como masa dividida por volumen: .m/V donde es la densidad, m es la masa y V es el volumen. En algunos casos (por ejemplo, en la industria del petróleo y el gas de los Estados Unidos), la densidad se define libremente como su peso por volumen unitario, aunque esto es científicamente inexacto – esta cantidad se llama más específicamente peso específico.

A 4 kg bowling ball moving at 1.4 m/s east impacts a 400 g pin that is stationary. After the impact, the ball is moving at 0.5 m
nignag [31]

The speed of the pin after the elastic collision is 9 m/s east.

<h3>Final speed of the pin</h3>

The final speed of the pin is calculated by applying the principle of conservation of linear momentum as follows;

m1u1 + mu2 = m1v1 + m2v2

where;

  • m is the mass of the objects
  • u is the initial speed of the objects
  • v is the final speed of the objects

4(1.4) + 0.4(0) = 4(0.5) + 0.4v2

5.6 = 2 + 0.4v2

5.6 - 2 = 0.4v2

3.6 = 0.4v2

v2 = 3.6/0.4

v2 = 9 m/s

Thus, The speed of the pin after the elastic collision is 9 m/s east.

Answer:

31,360J

Explanation:

Gravitation potential energy (gpe) is calculated from the formula mgh.

That implies, gpe = mgh

Therefore substituting the values of m and h as given in the question, knowing in mine that the acceleration due to gravity( g) is 9.8 N/kg, will give 31,360J

Never forget to put your SI units, because even if your answer is numerical correct, it will be incorrect because it represents no physical quantity.
