Processing every possible combination of the letters DBRI to arrive at the word BIRD is an example of the use of

an algorithm

Explanation:

In simple words, An algorithm can be defined series of guidelines programmed for a particular purpose to be carried out. This may be a basic procedure, such as combining two figures, or a complicated process, including such processing a video file that is condensed. Algorithms are also developed as features in software engineering.

Thus, from the above we can conclude that the correct answer is an algorithm.

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
