The route followed by a hiker consists of three displacement vectors a with arrow, b with arrow, and c with arrow. vector a with arrow is along a measured trail and is 1550 m in a direction 25.0° north of east. vector b with arrow is not along a measured trail, but the hiker uses a compass and knows that the direction is 41.0° east of south. similarly, the direction of vector vector c is 20.0° north of west. the hiker ends up back where she started, so the resultant displacement is zero, or a with arrow + b with arrow + c with arrow = 0. find the magnitudes of vector b with arrow and vector c with arrow.

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
