Respuesta :
a). The truck's distance covered for the trip is
(60) + (60 - 15) = 105 kilometers .
b). Its displacement for the whole trip is the distance
and direction from the start-point to the end-point.
15 kilometers east .
Answer:
The total distance and total displacement of the truck are 105 km and 15 km in east.
Explanation:
Given that,
A truck moves 60 Km east from point A to point B.
At point B , it turns back west and stop 15 km away from point A.
We need to calculate the total distance
[tex]d= d_{A}+d_{B}[/tex]
Put the value into the formula
[tex]d =60+45[/tex]
[tex]d=105\ km[/tex]
We need to calculate the displacement of the truck
Using formula of displacement
[tex]D=x_{A}-x_{B}[/tex]
Put the value into the formula
[tex]D=60-45[/tex]
[tex]D=15\ km[/tex]
Hence, The total distance and total displacement of the truck are 105 km and 15 km in east.
