Well, the problem is from webassign. And the way it wants me to put answers in is by multiples of the unit or multiples of gravity, mass, velocity, etc. The reason why I got 1 and 0 is because at the top of the swing, the centripetal acceleration is mg=(mv^2)/r which comes out to be a = g. So...
Homework Statement
Bob picks up a bucket of water by a rope and swings it around in a vertical plane. The bucket passes through the top of the circle with a speed v1.
(Note: You may neglect air resistance.)
a.)At point 1 (top of the loop):
How large is centripetal acceleration of the bucket...
