Question

A room has dimensions of 4 m x 3 m x 5 m. An insect moves from one vertex to diagonally opposite vertex on the cube. The magnitude of displacement of the insect will be

V2 m

52 m

V34 m

5
​

Answer 1

AB displacement, t=2s

And (AC+BC) is the distance

AB=

m/s

Average distance=12+5=17m

Average speed=

17

m/s

Average speed:Average velocity=

(13/2)

(17/2)

=
