Question
An insect of mass m, starts moving on a rough inclined surface from point A. As the surface is very sticky, the coefficient of friction between the insect and the incline is μm = 1. Assume that it can move in any direction ; up the incline or down the incline then
Options
A.The maximum possible acceleration of the insect can be 14 m/sec2
B.The maximum possible acceleration of the insect can be 2 m/sec2
C.The insect can move with a constant velocity
D.The insect can not move with a constant velocity
Solution
mgsin θ + mg cos θ = ma
a = g sin q + g cos θ
= 10
= 14 m/sec2. If fr = mg sinθ = mg ×
< fr max fr < fr max
=
hence insect canmove with constant velocity.
