1) Find an expression for the speed of the block if the coefficient of kinetic friction for the block on the table is μk.
2) Find an expression for the speed of the block if the table is frictionless.

Answer 1

interesting problem

Answer 2

can you help? @perl

Answer 3

hmm, this is tricky

Answer 4

there are two types of energy we can use here, potential and kinetic
