The wheel rolls without slipping on the horizontal surface, and the acceleration of its center of mass is o.531 m/s?. What is the magnitude of the frictional force on the wheel? Submit Answer Tries 0/15 What is the rotational inertia of the wheel about an axis through its center of mass and perpendicular to the plane of the wheel? Submit Answer Tries 0/15

The uniform solid block in the figure has mass 25.9 kg and edge lengths a = 0.763 m, b-1.40 m, and c=0.114 m. Calculate its rotational inertia about an axis through one corner and perpendicular to the large faces. Rotation asis Number Units

A solid sphere of mass 10 kg and radius 5 m rolls down an incline that is 20 m high. What is its approximate linear velocity when it reaches the bottom if it rolls without slipping? Use I = 2/5 MR^2 for the moment of inertia

In the figure, two 6.90 kg blocks are connected by a massless string over a pulley of radius 1.10 cm and rotational inertia 7.40 x 10-4 kg-m². The string does not slip on the pulley; it is not known whether there is friction between the table and the sliding block; the pulley's axis is frictionless. When this system is released from rest, the pulley turns through 0.900 rad in 148 ms and the acceleration of the blocks is constant. What are (a) the magnitude of the pulley's angular acceleration, (b) the magnitude of either block's acceleration, (c) string tension T1, and (d) string tension T2? Assume free-fall acceleration to be equal to 9.81 m/s?. (a) Number i Units (b) Number Units (c) Number Units (d) Number Units >
