Step 1

Let vu be the velocity of the ice cube at upper surface of the pipe, vb be the velocity of ice cube at lower surface after sliding down, g be the acceleration due to gravity, D be the diameter of the pipe, and m be the mass of the ice cube.

Write the given values of question.

1= 2 m/s
g 9.8 m/s
D 20 cm
