Kinematics
Hi

I'm trying to do these two questions.

For the 1st Question B=at (Im presuming) from a=an+at

From this at=R*alpha

Therefore 6.3=0.35*alpha

Then what formula do you use? you cant really use w=wo+alpha*(t) because u dont know the time nor the angular velocity
you cant use alpha*d(theta)=wdw either

So im stuck here on Q1

In regards to Q2

Would you do the same as in the question in this thread I posted early but differentiate again to find the velocity along x? I tried to do this but I would come in to problems and get unrealistic answers.

Tell me what you think

All Help would be most appreciated!
