Question

Calculator increase in internal energy of the tie and spike

Answer 1

Internal energy is a concept in physics that refers to the total energy of a system, including its kinetic and potential energies. When the internal energy of an object increases, it means that the object has gained energy. This can happen through various processes, such as heat transfer or work done on the object.

Step-by-step explanation:

Internal energy is a concept in physics that refers to the total energy of a system, including its kinetic and potential energies. When the internal energy of an object increases, it means that the object has gained energy. This can happen through various processes, such as heat transfer or work done on the object.

For example, if heat is transferred to a system and work is done on the system, the internal energy will increase. On the other hand, if heat is transferred out of the system and work is done by the system, the internal energy will decrease.

In the given context of a tie and spike, it is unclear what specific scenario is being referred to. However, the concept of internal energy applies in the same way - if energy is added to the tie and spike system, the internal energy will increase.

Answer 2

1.24 joules

STEP-BY-STEP EXPLANATION:

Mass (m) = 0.63 kg

Speed (v) = 2.5 m/s

Absorbed percent (p) = 62.9%

The increase would be the product between the kinetic energy and the absorbed percent, we substitute and calculate as follows:

`\begin{gathered} E=p\cdot K \\ \\ K=(1)/(2)\cdot m\cdot v^2 \\ \\ \text{ Therefore:} \\ \\ E=p\cdot(1)/(2)\cdot m\cdot v^2 \\ \\ \text{ We replacing} \\ \\ E=0.629\cdot(1)/(2)\cdot0.63\cdot2.5^2 \\ \\ E=1.24\text{ J} \end{gathered}`

The increase in kinetic energy was 1.24 joules
