Figure 5.15

A system comprising blocks, a light frictionless pulley, a frictionless incline, and connecting ropes is shown.  The 9 kg block accelerates downward when the system is released from rest.


In Figure 5.15, the acceleration of the system is closest to:

• 1.7 m/s²

• 1.9 m/s²

• 2.1 m/s²

• 2.3 m/s²

• 1.5 m/s²

2.1 m/s²
