Given:

Mass of Block A,

Height of inclined plane,

Angle of the inclined plane,

Coefficient of kinetic friction on the horizontal table,

Gravitational acceleration,

Time on the table,

 

Determine the speed of the block at the bottom of the inclined plane

First, we calculate the speed of Block A when it reaches the bottom of the inclined plane using energy conservation principles.

 

Potential energy at the top of the inclined plane:

The potential energy is given by:

where is the height of the inclined plane. The height , so:

 

Kinetic energy at the bottom of the inclined plane:

Since there are no other forces (apart from gravity) doing work on the block, all the potential energy is converted into kinetic energy. The kinetic energy is:

where is the velocity at the bottom of the incline.

 

Equating the potential energy to the kinetic energy:

 

So, the velocity of Block A when it reaches the horizontal table is .

 

Determine the frictional force on the block on the horizontal table

The frictional force on the horizontal table is given by:
