Hi, I'm actually working on a problem in Rotational mechanics. I'll just hint the problem. In a rotating body,tangential acc=(radius)angular acceleration. velocity=(radius)angular velocity.thus, [tangential acc/angular acceleration] =[velocity/angular velocity] can we use the theorems of ratio and proportions studied in algebra so as to write, [tangential acc+angular acceleration]/[tangential acc-angular acceleration] =[velocity+angular velocity]/[velocity-angular velocity] this was a q asked in my exam. still I have no idea whether my answer,Yes.we shall write is correct or wrong if u feel the answer is no plz justify.even if u feel yes,plz give me an explanation. thanks in advance.
