Objects with masses m_{1} = 10.0 kg and m_{2}= 5.00 kg are

connected by a light string that passes over a frictionless pulley

as in Figure P4.64. If, when the system starts from rest, m _{2} falls

1.00 m in 1.20 s, determine the coefficient of kinetic friction

between m _{1} and the table.

Step 1

Use the kinematics equation of position in terms of acceleration, in order to find the acceleration of the mass *m*_{2}.

Step 2

In the above equation the negative sign of the acceleration shows that the acceleration is towards downward.

Draw the free body diagram of the objects are:

For mass m1 and m2 are shown below:

Step 3

Write the force equation...
