Question

A physics book is moved once around the perimeter of a table with the dimensions 1.0 m by 2.0 m.

a: If the book ends up in its initial position, what is is its displacement?

b: What is the distances traveled?

Answer 1

(i)As the book ends up in the same position the displacement is 0 m.

(ii)The distance travelled is equal to the perimeter of the table i.e.

=2*(l+b)

=6m

Hope that this is helpful
