Blocks A (mA = 5.00 kg) and B (mB = 8.00 kg) are connected by a string that runs over an ideal, massless and frictionless pulley. The coefficient of friction between block A and the inclined plane is μk = 0.250. The system starts from rest. Use energy methods to determine the kinetic energy of block A after it moves a distance of 1.50 m along the inclined plane.(The angle block a is at is 30 degrees)

\

a.   What is the change in the potential energy of block A?         

\

      What is the change in the potential energy of block B?

\

 

\

b.   What is the work done by friction?               

\

c.   What is the common speed of the blocks?      

\

d.         What is the kinetic energy of block A?

\

 

\

Mass of the block A is 5 kg.

\

Mass of the block B is 8 kg.

\
\

The coefficient of friction between block A and the inclined plane is μk = 0.250.

\

Inclination angle is 30°.

\

Block A moves a distance of 1.50 m along the inclined plane.

\

 

\

Mass of the block A is 5 kg.

\

Mass of the block B is 8 kg.

\

The coefficient of friction between block A and the inclined plane is μk = 0.250.

\

Inclination angle is 30°.

\

Work done by the friction is given as \"\".

\

Where m is the mass of two blocks.

\

           g  is acceleration due to gravity (9.8 m/s²),

\

           μk  is coefficient of friction,

\

           \"\" is inclination angle.

\

\"\"

\

 

\

 Therefore work done by the frictional force is 10.60 J.
