Question

An object moves 3 metre not for me east and finally 6 metre South calculate the displacement

Answer 1

Explanation:

H2= b2 +p2

6^2=3^2+p2

36=9+P2

36-9=P2

UNDER ROOT 27=P

Answer 2

first it moves 3 m north

and then 6 m south

Net displacement=shortest path between the final and initial positions

=hypotenuse of the triangle formed

by pythagoreas theorem

hypotenuse=√(3²+6²)

=√45

=3√5 m

therefore displacement=3√5 m
