A person travels a distance of 4 m towards east, then 3 m towards south. Displacement of the person is

Answer»

Answer:

The displacement is 5m.

Explanation:

Given:

To the east = 4 m

To the SOUTH = 3 m

To find :

The displacement

Solution :

Displacement is the shortest distance travelled from the INITIAL point to the final point.

Distance to east (x) = 4 m

Distance to the south (y) = 3 m

Displacement =

★ \boxed{\sf{s =\sqrt{x^{2}+y^{2}}}}

⇒ s = \sf{\sqrt{4^{2}+3^{2}}}

⇒ s = \sf{\sqrt{16+9}}

⇒ s = \sf{\sqrt{25}}

⇒ s = 5

Displacement = 5 m

THEREFORE, the displacement is 5m.
