Question

A car moves 300 m due east and then 400 m due north .
1.what is the total distance covered by car?
2.what is total displacement?

Answer 1

Answer:

Explanation:

DISTANCE COVERED DUE EAST= 300 M

DISTANCE COVERED DUE NORTH=400 M.

(1) TOTAL DISTANCE COVERED= 400+300

                                                     =700 M

(2) DISPLACEMENT IS THE SHORTEST DISTANCE BETWEEN THE STARTING POINT AND ENDING POINT.

HERE NORTH AND EAST DIRECTIONS ARE PERPENDICULAR TO EACH OTHER,

THIS FORMS A RIGHT ANGLED TRIANGLE WITH BASE AS  300 M[ EAST]

ALTITUDE AS 400 M[NORTH]

HYPOTENUSE AS DISPLACEMENT.

HYPOTENUSE=√(400²+300²)

DISPLACEMENT= 500 M.

HOPE THIS HELPS.
