Question

1.A body is moving in a square of side 10 m. Calculate distance and displacement in
the following cases:
(a)    From A to B
(b)    From A to C
(c)    ABCDA

Answer 1

Explanation:

in case a:

distance=10m

displacement=10m

in case b:

distance=10+10=20m

displacement=underroot10^2+10^2

=underroot100+100

=10underroot2

in case c:

distance=10+10+10+10+10=50m

displacement=0
