Final answer:
The question as presented seems to be a mixture of physics and chemistry concepts mistakenly applied to a kite in geometry. Without the correct geometrical context, an accurate answer cannot be provided.
Step-by-step explanation:
The question seems to be about a geometrical shape, specifically a kite, and its properties. However, the information provided is disconnected and appears to be taken from various sources dealing with physics (impulse-momentum theorem) and with chemistry (enthalpy changes). Therefore, it appears that there has been a mix-up in the question. As such, without the correct context or a properly defined question related to a kite in geometry, providing an accurate answer is not possible.
If we were discussing a kite in geometry, you would normally use properties like congruent sides or diagonal lengths to solve for missing measurements. However, since the provided information is not pertinent to such a problem, it is best to ask the student for clarification on the question to ensure accuracy of the solution provided.
