physics help please

The two blocks are connected by a light
string that passes over a frictionless pulley with a negligible mass. The 3 kg block lies on a rough horizontal surface with a constant coefficient of kinetic friction 0:3. The hanging block has a mass of 8 kg. The system starts from rest. The acceleration of gravity is 9.8 What is the speed of the 8 kg hanging mass when it has fallen a height 8 m? Answer in
units of m/s.


daaang, I am glad I am not in your class.
I would be the dumb blonde there xD
Goodluck and best wishes!
