Problem Details

Use work and energy to find an expression for the speed of the block in the following figure just before it hits the floor.A figure shows a block of mass Upper M atop a level table with a coefficient of kinetic friction mu subscript k. A rope is tied to the side of the block and runs through a pulley on the edge of the table to another block of mass m. The block of mass m is suspended at a height h above the floor.

Find an expression for the speed of the block if the coefficient of kinetic friction for the block on the table is k.

Find an expression for the speed of the block if the table is frictionless.
