2. A cylindrical plug A of mass ma = 0.5
kg is released from rest at point B and
slides down smooth circular guide with a
radius r= 2 m, as shown in the Figure.
The plug strikes the block C of mass mc
= 1.2 kg and becomes embedded in it.
After the impact plug-block system
travel a rough surface S with coefficient
of kinetic friction Hk = 0.3. Neglect the
air friction for the following calculations.
(a)
path.
Calculate the work done on the plug due to the displacement in the circular
(b)
Calculate the velocity of the plug-block system just after the strike.
(c)
Before coming to rest how much distance the block and plug will travels. Also
calculate the deceleration rate in this distance.
A 15.0-kg bucket of water is suspended by a very light rope wrapped around a
solid uniform cylinder 0.300 m in diameter with mass 12.0 kg. The cylinder
pivots on a frictionless axle through its center. The bucket is released from rest
at the top of a well and falls 10.0 m to the water. (a) What is the tension in the rope while
the bucket is falling? (b) With what speed does the bucket strike the water? (c) write the
kinetic equation as the bucket sink into the water, suppose the resistance force is
proportional to the speed, the volume of bucket is V, and draw the free-body diagram.
A yo-yo is constructed of three disks: two outer disks of mass MM, radius RR, and thickness dd, and an inner disk (around which the string is wrapped) of mass mm, radius rr, and thickness dd. The yo-yo is suspended from the ceiling and then released with the string vertical (see figure below).
Calculate the tension in the string as the yo-yo falls. Note that when the center of the yo-yo moves down a distance y, the yo-yo turns through an angle y/r, which in turn means that the angular speed ω is equal to Vcm/r.
Use the following as necessary: M, R, d, m, r, and g for the acceleration due to gravity.)
