Question

A boy travels 10m east,12m north,10m due west and finally 8m due south.Find distance and displacement

Answer 1

Answer:

Explanation:

Let us take positive x axis in east.

Then x component of displacement is 8 m.

We take positive y axis in north. Then,

y component of displacement is 6 m.

We take positive z axis in vertically upward direction. This gives

z component of displacement is 10 m.

The displacement vector is (8,6,10) m

The magnitude of this vector is (64+36+100)^(1/2)=(200)^(1/2)=10 root2.

Answer 2

Answer:

distance 40m and displacement 4m
