# Come on lucky number seven

**Classical Mechanics**Level 5

A cubic dice is sliding on a frictionless table. The dice is a cube with edges of length 1 cm and a mass of 30 g. A kid reaches down and gives a horizontal flick to the dice, causing it to change which face is up. What is the minimum impulse in **g~cm/s** the kid must give to the dice in order to change the face?

**Details and assumptions**

- The acceleration of gravity is \(-9.8~m/s^2\).
- You can model the dice as a perfect cube of uniform density.
- The dice never leave the table
