What are some questions engineers should ask when researching a problem? Who will this help?

How long will it take to get it right?

What a materials can be used to solve the problem?

How much will the project cost?

What are the factors that affect the resistance of a wire?

If anyonee has done the momentum lab practical in physics can you give me the answers i am s lostt rnn : (

Estimate the kinetic energy of mars with respect to the sun as the sum of two terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. (assume mars is a uniform sphere with mass = 6.4×10 to the power of 23 kg, radius = 3.4×10 to the power of 6 m, rotation period = 24.7 hours, orbital period = 686 days and is 2.3×10 to the power of 8 km from the sun.)
