A pail of water is rotated in a vertical circle of radius 1.0 meter.
a) Find what two external forces act on the water in the pail?
b) Find which of the two is most important in causing the water to move in a circle?
c) Find the pail minimum speed at the top of the circle if no water is to spill out?
d) If the pail with the speed found in part (c) were to suddenly disappear at the top of the circle, explain the subsequent motion of the water. Would it differ from the motion of a projectile?
