A rod or length 2m starts to roll on a horizontal surface as shown in figure. At the same time an ant starts from one end of the rod to other and when the rod rools through a distance 10m the ant dreaches the other end (B). Calcualte the distance and displacement of the ant
(a) with respect to the rod
(b) with respect to the ground.

Text Solution

Verified by Experts

Distance travelled by the ant with respect to the rod = 2 m
Displacement with respect to the rod = 2 m
Distance with respect to the ground = 10 + 2 = 12 m
Displacement with respect to the ground
`=sqrt(2^(2)+10^(2)) =sqrt(4+100)=sqrt(104)m`
