During construction of the new large apartment building in Midtown, a piece of glass fell from the top of the building. The glass crashed onto the busy 57" street sidewalk below and injured 3 people. The
new apartment complex has a height of 426 meters. Suppose the glass fell from the top of the building
at rest.

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
