Question

If the coefficient of friction between an insect and a bowl is "u" and the radius of the bowl is "r". Find the maximum height to which the insect can crawl up in the bowl.

Answer 1

i think the answer to this question is perhaps r, because when it becomes horizontal the friction force would be zero as normal reaction is zero. otherwise the force provided by the insect to accelerate in forward direction might be sufficient to overcome frictional and gravitational forces.
