Determine the displacement and distance covered by a man if he walks 10 m north, turns east and walks 20m, and then turns left and walks 10 m.

His displacement is about 44.72 and he covered 40m

Answer : his displacement is 44.72 . Explanation : He displaced around 44.72 and covered 40m

As newton's first law states a object in motion stays in motion

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
