One pulley attached between two blocks, both sliding on wood.

SUMMARY

The discussion focuses on solving a physics problem involving two blocks connected by a pulley, both sliding on wood. The key equations include the frictional force equation Fk=UkN, where Uk represents the coefficient of kinetic friction and N is the normal force. Participants emphasize the importance of setting up separate equations of motion for each block, accounting for forces such as tension, normal force, and weight. The solution involves isolating variables to solve for the mass of block one (m1) using the relationship between the tensions in the ropes.

PREREQUISITES

You need to set up an equation of motion for block one and block two separately. You can also use the fact that the tension in the rope attached to block 1 is equal to the tension in the rope attached to block 2. Then you can solve for m1.
 
how would i do that?
 
Find all the forces acting on block 1 and set that equal to m1a. Then find all the forces acting on block two and set that equal to m2a. Then by solving for T, you can get the equation down to one variable and solve for m1.
 
Okay block 2 has:
Normal force
Friction
Tension
Weight of 49

Block one has:
normal force
Tension
and Weight

Please! help me get started!
