Question

a person travels towards north by 4m and then turns to west and travels by 3m. The distance and displacement are​

Answer 1

Answer:

The final answer is

1) Distance = 7m

2) Displacemetn = 5m

Explanation:

Given,

A person travels towards the north by 4m. Then travels to the west by 3.

We need to find the total distance and the total displacement he has travelled.

Total distance is simply the total distance travelled by the the person.

Total distance = Distance travelled in North + Distance travelled in West

= 4 + 3

= 7m

Displacement be found using the vertical and horizontal componnent of the distance travelled. Displacement is the position an object is at after unit time from its original position.

Vertical componnent = 4 * sin 90 = 4

West Componnent = 3 * sin 180 = 3

Displacement = $\sqrt{3^2 + 4 ^ 2}= \sqrt{16 + 9}$ = $\sqrt{25}$ = 5m
