Question

A man walks 3m in east direction after some time it turns to the left and travels a distance of 4m.What is the magnitude and direction of the displacement?​

Answer 1

Answer:

so the man walk total 7 meater

Answer 2

Answer:

5m

to find displacement:

use  hypotheneus

a^2 + b^2 = c^2                     (x = displacement)

3^2 + 4^2 = x^2

9 + 16 = x^2

x^2 = 25

x = root25 = 5

displacement = 5m

distance = 3+4 = 9m
