```					SPH 4U            Incline Plane and Pulleys Problem Set
Find the acceleration of the system and the tension in the string for each of the systems below.
Assume the string is light and non-stretching and the pulley is frictionless.

1.                                                                                mA   =   40.0 kg
mB   =   5.0 kg
μs   =   0.40
μk   =   0.30
A                                                 g    =   9.8 N/kg
B
25°

2.                                                                                mA   =   26.0 kg
mB   =   4.0 kg
μs   =   0.80
μk   =   0.75
A                                           g    =   9.8 N/kg

45°

B

3.                                                                                mA   =   40.0 kg
mB   =   5.0 kg
μs   =   0.40
μk   =   0.30
A                                       B                    g    =   9.8 N/kg

60°                               30°
