An 80-Cm Radius Disk with a Rotational Inertia of 0

question 76

Multiple Choice

An 8.0-cm radius disk with a rotational inertia of 0.12 kg .0 m² is free to rotate on a horizontal axis. A string is fastened to the surface of the disk and a 10-kg mass hangs from the other end. The mass is raised by using a crank to apply a 9.0-N.m torque to the disk. The acceleration of the mass is:

• A) 0.50 m/s²
• B) 1.7 m/s²
• C) 6.2 m/s²
• D) 12 m/s²
• E) 20 m/s²
