Angela has a bucket of mass 2 kg tied to a string. She places a drinking glass of mass 0.5 kg in the bucket. SHe spins the bucket in a vertical circle of radius 1.5 m. b.) What is the equation for the net force on the glass at the top of the circle in terms w, Fn, m, v, and r? c.) The glass will fall out of the bucket if the normal force between the glass and bucket equals zero. How fast must she spin the bucket to prevent this from from happening? d.) The string will break if the tension on it is more than 100 N. Over what range of speeds can she keep the glass in the bucket and prevent the string from breaking?
