Answer:
Duration of the total trip
Explanation:
Acceleration is defined as the rate of change of velocity of an object:
where
is the change in velocity
is the duration of the change in velocity
Acceleration is measured in meters per squared seconds, . Also, we should note that acceleration is a vector quantity, so in order to completely define acceleration we also need to specify the direction.

Answer:
The question clearly describes the circular motion.
The circular motion equation is
The path of the particle is circular.
Explanation:
In circular motion, the radial acceleration is always towards the center and constant in magnitude. Furthermore, the velocity of the circular motion is always tangential to the circle, that is it is always perpendicular to the radius, hence the acceleration.
