Question

In the process of delivering mail, a postal worker walks 161 m, due ease from his truck. He then turns around and walks 294 m in the west direction and then walks another 100 m in the east direction. What is the worker's displacement relative to his truck?

Answer 1

The displacement is 33 m due west

Step-by-step explanation:

From the question we are told that

The first displacement due east is
`d_e = 161 \ m`

The displacement due west is
`d_w = 294 \ m`

The second displacement due east is
`d_(e_2) = 100 \ m`

Generally the displacement is mathematically represented as

`D = d_e + d_(e_2 ) - d_w`

=>
`D =  161 +  100 -  294`

=>
`D =  -33 \  m` Note [-ive] represents west [+ive] represents east

Which means that the displacement is 33 m due west
