The next four questions pertain to the situation described below.
Two coaxial solid disks are glued together and placed on a common axle
passing through the center of mass of the disks normal to their circular
cross sections. A constant 80 N force F is applied at the rim of the larger
disk by a string wound around its rim (the string is not shown in the
figure). The string does not slip. The radii of the smaller and larger disks,
and are 0.6 m and 0.8 meter, respectively, but the disks have
identical masses M
. The disks are initially at rest. At t = 0 the disks are
allowed to rotate.

angular acceleration of the larger disk alone, , relate to the angular acceleration of the system of two disks,
,measured previously? a. b. c. d. e. The next four questions pertain to the situation described below.

initially at rest and oriented perpendicular to the path of the block. Everything
is on top of a horizontal frictionless table, and the rod has a fixed frictionless
pivot through its end that allows it to rotate freely but keeps its end from
moving. After the block hits the rod they rotate together with a constant angular velocity of = 5.5 rad/sec. What was the initial
speed of the block?

cylinder with their backs against the wall.. The cylinder begins to rotate about a vertical axis. Then the floor on
which the passengers are standing suddenly drops away! If all goes well, the passengers will "stick" to the wall
and not slide. Clothing has a static coefficient of friction against steel in the range 0.60 to 1.0 and a kinetic
coefficient in the range 0.40 to 0.70.
