Question

An insect moves along a circular path of radius 10 cm with constant speed. If it takes 1 min. to
move from a point on the path to the diametrically opposite point, find
(a) the distance covered,
(b) The speed,
(c) the displacement,
(d) average velocity.

Answer 1

Answer:

Correct option is

B

31.4 cm, 0.33 cm s

−1

Distance =π∗r=10∗3.14=31.4cm.

Time 1min=60s

displacement =20cm,

velocity=

time

displacement

=

60

20

=
