Answer:
Correct answer: Cf = tan 33° = 0.649 (I guess you meant degrees and not minutes)
Explanation:
The horizontal component of the object's weight equals to the force of friction and the object is just about to slide.
The horizontal component of the object's weight is Qh = mg sin 33°
The force of friction is Ffr = Cf · Qv = Cf · mg cos 33° , where Cf is the coefficient of static friction and Qv vertical component of the object's weight
Qh - Ffr = 0 => Qh = Ffr => mg sin 33° = Cf mg cos 33°
we divide both sides of the equation by mg and get:
Cf · cos 33° = sin 33° => Cf = sin 33° / cos 33° = tan 33° = 0.649
Cf = 0.649 the weight of the object is unnecessary data

Army and Ellie left school at the same time.
Army lives farther than Ellie.
They arrived at their homes at the same time.
This means that Army travels faster than Ellie.
Time
Since the time is constant here, increasing the distance directly increases the speed.

Answer:
17.00 N
Explanation:
Given that the x-component of a vector is 17, and the angle between the vector and the x-axis is 46 degrees
The magnitude of the vector will be calculated by first resolving the vector into x component and y component.
X - component
17cos46 = 11.809
Y component
17sin46 = 12.229
We will find the resultant vector by using pythagorean theorem
R = sqrt ( X^2 + Y^2 )
R = sqrt ( 11.809^2 + 12.229^2 )
R = sqrt ( 288.995 )
R = 16.999
R = 17.00 N
Therefore, the magnitude of the vector is 17 .00N
