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?

What is the magnitude of the acceleration of a modified Atwood machine if the mass of the cart is 3 kg and the hanging mass is 12 kg
Interestingly, there have been some studies using cadavers to decide the moment of inertia of human body parts by letting them swing as a pendulum about a joint. In one study, the center of gravity of a 5.0 kg lower leg was found to be 18 cm from the..
