A 27.76 N crate is being lowered down at a constant rate along an inclined ramp by a massless rope. Find the magnitude of force F in N if the angle between the ramp and the horizontal is 30 degrees and coefficient of kinetic friction is 0.2. See the figure attached. My attempt at solution:

Sum F y = 0
F y = F n - F g y
F n = m g cos(30)

Sum F x = F g x - F - f k = 0
F = F g x - f k
F = m g sin(30) - mu k Fn
F = m g sin(30) - 0.2(m g cos(30))

F = 27.76sin(30) - 0.2(27.76cos(30))
F = 9 N

i think its c if i'm wrong

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
