Please this is a Gordon Rule question derived from 7th or8thedition of general physics by James and susan Walker Q#1 (a) can a centripital force ever do work on an object? .pleaseexplain in great detail. (b)why is it easier to climb a steep mountain via azigzagtrail (switchbacks) than to climb straight up? (c) how could a small force ever exert a greate torque thanalarger force? . please explain in detail. (d) explain how conservation of angular momentum applies toanice skater spinning on the ice.
