QUESTION 2 (Start on a new pago.) A billboard, mass 15 kg. is suspended from a roof by means of a light inextensible
string. Force F pulls the billboard sideways, as shown in the diagram below.
40°
string
15 kg
When the angle between the roof and the string is 40', a closed vector diagram is
obtained for all the forcos acting on the billboard.
2.1
What deduction can be made when the forces acting on an object forms a
closed vector diagram?​

Simple harmonic motion wind energy circulation best answer from the choices

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
