Question

a car moves 100 m due East and then 25 n due north, find distance and dissplacement covered by a car​

Answer 1

Explanation:

Distance covered= 100 m + 25 n

= 25(4 m +n) unit

By pythagorus theorem

(100m)^2+(25n)^2=Displacement^2

=10000m^2+625n^2

=25(400 m^2 + 25n^2)

Displacement= root25(400 m^2 + 25n^2)

= 5root(400 m^2 + 25n^2)
