Answer :
The minimum speed that the bucket must swing so that the bucket does not come crashing down at the top of its loop is v = [tex]\sqrt{rg}[/tex]
Fc = Fg
mac = mg
ac = g
ac = v^2/r
v^2/r = g
The pace at which the distance a moving item travels changes is measured as speed. Since speed is a scalar, it has magnitude but no direction as a unit of measurement.
Speed is the rate at which anything moves over a predetermined distance.
an object that moves quickly and with high speed, covering a lot of ground in a short time. A slow-moving object with a low speed, on the other hand, covers a comparatively short distance in the same amount of time. An item with zero speed is stationary.
