A Mass M = 4

question 35

Multiple Choice

A mass m = 4.0 kg is connected, as shown, by a light cord to a mass M = 6.0 kg, which slides on a smooth horizontal surface. The pulley rotates about a frictionless axle and has a radius R = 0.12 m and a moment of inertia I = 0.090 kg⋅m². The cord does not slip on the pulley. What is the magnitude of the acceleration of m?

• A) 2.4 m/s²
• B) 2.8 m/s²
• C) 3.2 m/s²
• D) 4.2 m/s²
• E) 1.7 m/s²
