I get it, but I think it needs to be T cos theta=mg and T sin theta =ma and then when you divide you divide Tsintheta=ma/T cos theta=mg which leaves u with Sintetha=a/Cos theta=g so Tantheta=a/g and then rearrange to get a=gtantheta... so thanks! a lot!
Thats my thoughts exaclty! It is this rubber stopper of mass m is in a car and then when the car accelerates it makes an angle with the veritcal which is theta. We are supposed to find a=gtantheta in terms of mass and L, which must be radius, cause the
that should be a= gtan? (theta, not ?)
