China Traditional Acrobatics Project Water Meteor

(1) When the water just doesn't overflow when the bucket passes the highest point, the pressure on the water at the bottom of the bucket is 0, if there is mg=mV20r. , then v0 = gr =10m/s.

(2) At the lowest point: F-mg=mV2r, substitute the data F= 1 10N to get v =10m/s. 。

Answer: (1) The minimum speed when passing through the highest point is10m/s.

(2) The maximum speed when passing through the lowest point is10m/s.
