An insect of mass 'm' is initially at one end of a stick of length 'l' and mass 'M'.The coefficient of friction between the insect and the stick is 'k'. The minimum time in which the insect can reach the other end of the stick is 't', then #t^2#?
1 Answer
Given that the mass of the insect is
Considering that the stick on which the insect moves is in horizontal position.
The normal reaction on the insect will be equal to its weight
Hence the maximum frictional force will be
Hence the maximum acceleration with which the insect can move over this stick will be
Starting from rest if the insect takes minimum time
