Question

If a boy runs 125 meters north, and then 75 meters south, his total displacemen5 is

Answer 1

Note: Initial motion = 125 meters to the north

Final motion = 75 meters to the south

Asked: Total displacement

Answer: Total movement = initial motion + final motion

(Because the ultimate motion is opposite that the formula is)

Total displacement = Initial motion - End movement

= 125 meters - 75 meters

= 50 meters

So, the whole displacement of the boy is 50 meters.

Further Explanation

Displacement is that the shortest distance from the ultimate position and therefore the initial position of an object. distance this idea is commonly exchanged with the concept of distance. Displacement are often written as

d = r1 - r2

Displacement could be a change within the position of an object in an exceedingly certain interval and could be a vector quantity. Displacement is said to position transfer. the number of displacement depends only on the starting position and therefore the final position.

Distance could be a number that shows how far an object changes its position through a particular path. In physics or everyday terms, distance are often an estimate of the physical distance of two positions supported certain criteria. In mathematics, the gap must meet certain criteria.

Unlike the position coordinates, the gap might not be negative. Distance could be a scalar quantity, while displacement could be a vector quantity. the gap traveled by a vehicle (usually indicated on the odometer), person, or object, must be distinguished from the gap between points.

In physics, distance is that the length of the trail taken by a moving object, ranging from the initial position and finishing at the ultimate position. this idea is commonly exchanged with the concept of displacement.

Answer 2

Answer:  50 m

Consider the figure below: Let O be the starting reference point. The boy runs northwards 125 m and then 75 m southwards.

Displacement is the shortest path traveled from the reference point. Distance is the total path length traveled. Hence, the distance would be 125 +75 =200 m but the displacement would be $125-75 =50 m$.
