The friction coefficient between the object and the table is u. The displacement s caused by pushing the object with force F is to remove F, How far can an object go

The friction coefficient between the object and the table is u. The displacement s caused by pushing the object with force F is to remove F, How far can an object go

Acceleration A1 in the presence of F = (f-umg) / M
The acceleration after f is removed A2 = UMG / M = UGF, the velocity when f is removed v = root sign (2a1s)
The forward distance after removing x = V ^ 2 / 2A2
The result is x = (f-umg) s / (UMG)
PS: I can't get the root and the score, please forgive me,
