Question

a man goes 12m east and 35m north . What is his original position
​

Answer 1

Step-by-step explanation:

Displacement=final position-initital position

Let's the starting point be O

From O he is going at point A in south whose distance from O is 12 m

From A he is going at point B in west whose distance from A is 35m

If we join all three points together we got a right angle triangle OAB.

WHOSE OA=12m=a

AB=35M=b

according to pithagoras theoram

BO=UNDERROOT(a^2+b^2)

=underroot(12^2+35^2)

=underroot(144+1225)

=underroot(1369)

=underroot(37×37)

=+-37

since displacement cant be negative so the answer will be 37m.

Now ,displacement is a vector by the triangle law of vector we can say that the direction of resultant or displacement is from south west.
