Answer:
The answer is 20727w
Explanation:
The formula is below;
P = d r^2 v^3 *efficiency
In the question, it is stated that the registration ignores efficiency so we are going to ignore efficiency in the equation and use it this way;
P = d r^2 * v^3
d =4.3, r = 1.59, v =n 12.4
Therefore, P = 4.3 X 1.59^2 X 12.4^3 = 20727W
Answer:
2632 foot-pound
Explanation:
Work done: Work is said to be done when ever a force moves a body through a given distance. The S.I unit of force is Newton (N).
From the question,
The expression for work done is given as,
W = Fdcos∅......................... Equation 1
Where W = work done, F = force, d = distance, ∅ = angle between the force and the horizontal.
Given: F = 32 lbs, d = 90 feet, ∅ = 24°
substitute into equation 1
W = 32×90×cos24
W = 2880(0.914)
W = 2632.32
W = 2632 foot-pound
