: A 100 kg box is initially at rest on a horizontal surface where the coefficient of friction is 0.25. A tension force of 1000 N is exerted on the box at an angle of 37 degrees from the horizontal. What is the normal force acting on the box?What is the acceleration of the box?

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 

Ibelieve the answer is either b or c, but i'm leaning more towards c.hope my answer has you : )

Idk just need points
