But wouldn't acceleration be decceleration because it would slow down as it goes?
But that's weird because as its pushed, the acceleration would have to rise, but it will slow down eventually so its decelerating.
This problem sucks.
Well, so how could I answer b,c,d? I'm looking for an answer if you don't mind, not just some help.
I want to discuss this with the professor when I get the chance. I even asked the tutor at school and he's says he's in a huge disagreement with her over this problem.

I don't know about that... ANGULAR ACCELERATION is described as w(omega) w2-w1/t2-t1
Is w supposed to be the distance?
And I still have no idea on the linear acceleration.
maybe V-Vinitial/t ?
it is pushed by someone and stopped by the person on the other end of that 3.5m. So since it was rolled by someone, I would assume initial velocity is 0 until it is rolled.
She may want us to assume something but I'm not sure and can't ask her for a while. There just isn't enough info I think. here it is.
A ball is rolled on level floor a distance of 3.5m to another person. The ball made 15 revolutions.
a) asked for diameter of the ball which is easy and I...
