Which of the following answers describe how to calculate the acceleration of an object?
a. divide the change in the objects velocity by the time it takes to make that change.
b. divide the time the object travels by the distance it travels.
c. calculate the distance the object travels and divide that by the time it takes to get there.
d. calculate the velocity of an object and divide that by the time the object is in motion.

I think it's A I hope this is right but I just studied this so I think this is the right answer

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
