Asha walks 15 m west, then 20 m north, then 15 m east. Calculate the distance and displacement covered by Asha.(a) (Numbering problem)_

Asha traveled a distance of 50 m

The displacement is 20 m north.

Explanation:

Distance and Displacement

A moving object constantly travels for some distances at defined periods of time. The total moved distance is the sum of each individual distance the object traveled. It can be written as:

dtotal=d1+d2+d3+...+dn

This sum is obtained independently of the direction the object moves.

The displacement only takes into consideration the initial and final positions of the object while moving. The displacement, unlike distance, is a vectorial magnitude and can even have magnitude zero if the object starts and ends the movement at the same point.

Asha walks 15 m west, 20 m north, and 15 m east. The total distance is

dt=15 m + 20 m + 15 m = 50 m

Asha traveled a distance of 50 m

Note the final position is 20 m above the initial position since she goes 15 m west and 15 m east. Thus the displacement is 20 m north.

double the distance = divide strength by 4

where’s the list ? the question is incomplete
