Problem 5: A heavy wheel of radius 20 cm is mounted on a horizontal axle. A rope wrapped around its rim is pulled straight downward with a constant force of 50 N. The rope moves a distance of 50 cm in 1.0s. a) What is the angular acceleration of the wheel? b) What is the moment of inertia of the wheel? c) The wheel is a homogeneous, solid disk. What is its mass? Solution: (a) 5 rad/s; (b) 2 kg-m2; (c) 100 kg Problem 5: A heavy wheel of radius 20 cm is mounted on a horizontal axle.
