a) what two external forcces act on the water in the pail?

c) What is the pail's minimum speed at the top of the cricleif no water is to spill out?
d) If the pail with the speed found in part (c) were tosuddenly disappear at the top of the circle, describe thesubsequent motion of the water. Would it differ from the motion ofa projectile?
