Suppose that a group of researchers would like to explore how we perceive objects in the real world, rather than just in a laboratory. this approach emphasizes:

ecological validity.

Explanation:

Ecological validity: The term ecological validity is defined as the limit or extent to which a particular findings of specific research study can be generalized into real-life settings. If the ecological validity of a particular study is considered to be high then it is believed that the behavior being recorder from the research can be applied in day to day life and it signifies that the result is considered to be as useful.

In the question above, the approach emphasizes the ecological validity.

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

answer; i believe the answer is 80%, plz check first good luck;
