Question

A robotic car, moving 54 meters east then 25 meters north. For the testing, it travelled another

18 meters west then 9 meters south. Calculate the total displacement.

Answer 1

Step-by-step explanation:

Given:

SE = 54 m

SN = 25 m

SW = 18 m

SS = 9 m

________

S - ?

Sx = SE - SW = 54 - 18 = 36 m

Sy = SN - SS = 25 - 9 = 16 m

The total displacement:

S = √ ( (Sx)² + (Sy)² ) = √ ( 36² + 16² ) = √ (1296 + 256) =

= √ (1552) ≈ 39 m
