Question

3. A car covers 6 Km towards West, then 5 Km towards North and finally 2 Km again towards West. Calculate the distance travelled and displacement of the car

Answer 1

Answer:60km

Explanation:

Answer 2

Answer:

Distance = 13 km

Displacement =  $\sqrt{89}$ km  ( simply 9.434 km ).

Explanation:

distance = total distance actually covered

              = 6 + 5 + 2

              = 13 km

displacement = shortest distance between two points.

let's take the initial position in graph as (0,0)

after 6 km west we will be at (-6,0)

after 5 km north we will be at (-6,5)

after 2 km west we will be at (-8,5)

now,

displacement = distance between the points (0,0) and (-8,5).

by applying the distance formula,

we get displacement = $\sqrt{89}$ km.
