Answer:
25 N
Explanation:
Use the equation F = m(Vf–Vi) / Δt.
average force = mass (final velocity - initial velocity) / change in time
F = 40 kg(5.0 m/s) / 8.0 s = 200 / 8.0 = 25 kgm / s^2 = 25 Newtons
X(x-2) = 15 where x = the unknown number
If you test all the answers in that equation, both x values in answer A yield 15, so the answer is A
or 5 lengths of 234 feet to be cut from a board, the board must have a length of at least 1170 feet.
Let x represent the total length of the board so as to allow for the cutting of 5 lengths.
Since each length needed to be cut is 234 feet, hence:
x = number of lengths × feet per board
x = 5 lengths × 234 feet
x = 1170 feet
Hence for 5 lengths of 234 feet to be cut from a board, the board must have a length of at least 1170 feet.

Musculoskeletal Health can be efficiently maintained by proper nutrition and regular physical exercise programs.
<h3>What does musculoskeletal health mean?</h3>
The expression 'musculoskeletal health' makes reference to the activities aimed at preserving the health of the muscles and skeletal system.
The muscles that are attached to the skeletal system are called skeletal muscles, and they can be maintained by proper nutrition (consuming proteins) and physical exercise.
Moreover, the bones of the skeletal system need calcium to maintain their strength and rigid structure.
In conclusion, musculoskeletal health can be efficiently maintained by proper nutrition and regular physical exercise programs.
