A bucket full of water is rotated in a vertical circle of radius 0.837 m (the approximate
length of a person’s arm).
What must be the minimum speed of the
pail at the top of the circle if no water is to
spill out?
Answer in units of m/s

Answer in units of m/s
-
a = v^2/r
acceleration must be equal to gravity to keep water from falling
9.81m/s^2=v^2/.837m
v=2.87m/s
