Richard wants to write a research proposal. the subject he is interested in does not have a lot of preexisting knowledge surrounding it. thus, he will be asking basic questions to his research participants. what kind of research approach will he likely be taking?

qualitative research

Explanation:

                     Richard, a research scholar, wanted to do a research study in a subject which does not have a lot of preexisting knowledge. SO he will have to ask basic question to his research subjects in order to get an overall idea about the topic. By doing such he will be able to gain a basic knowledge about the subject he had chosen.

                     Qualitative research is done to obtain or which aims at expanding and gaining knowledge by asking basic question research participants related to the subjects.

Thus the answer is qualitative research.

a. formula: f=ma or f/m=a

10,000n/1,267kg≈7.9m/

b. formula: a= and s=d/t

speed= 394.6/15

s=26.3m/s

a=

a=1.75m/

c. 7.9-1.75=difference of 6.15m/

d. the force that most likely caused this difference is friction forces
