Question

a 20.00-kg box is attached to a light string that is wrapped around a cylindrical frictionless spool of radius 15.0 cm and mass of 5.00 kg. The spool is suspended from the ceiling, and the box is then released from rest a distance 4.50 m above the floor.

What is the acceleration [in m/s^{2}] of the box?

How long does it take [in s] for the box to reach the floor?

Answer #1

A 90 kg mass is tied to a massless rope wrapped around a solid
cylindrical drum, mounted on a frictionless horizontal axle. When
the mass is released, it falls with acceleration 3.4 m/s2 .
a. Find the rope tension. Express your answer in
newtons.
b. Find the drum's mass.

An object with a mass of m = 5.5 kg is attached to the free end
of a light string wrapped around a reel of radius R = 0.260 m and
mass of M = 3.00 kg. The reel is a solid disk, free to rotate in a
vertical plane about the horizontal axis passing through its center
as shown in the figure below. The suspended object is released from
rest 6.40 m above the floor. (a) Determine the tension...

A bucket of water of mass 15.9 kg is suspended by a rope wrapped
around a windlass, that is a solid cylinder with diameter 0.350 m
with mass 12.4 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 a distance 10.2 m to the water. You can ignore the
weight of the rope.

Two metal disks are welded together and mounted on a
frictionless axis through their common centre. The radius,
R1 of the first one is 2.5cm and its mass, M1
is 0.8 kg. The radius of the second disc, R2, is 5 cm
and its mass, M2, is 1.6kg. A light string is wrapped
around the edge of the smaller disc and a 1.5 kg block is suspended
from the end of the string. If the block is released form rest...

A 12.0-kg box resting on a horizontal, frictionless surface is
attached to a 5.00-kg weight by a thin, light wire that passes
without slippage over a frictionless pulley. The pulley has the
shape of a uniform solid disk of mass 2.40 kg and diameter 0.420
m.
A)After the system is released, find the horizontal tension in
the wire.
B) After the system is released, find the vertical tension in
the wire.
C)After the system is released, find the acceleration of...

A 4.00 kg stone is tied to a thin, light wire wrapped around the
outer edge of the uniform 10.0 kg cylindrical pulley shown in the
figure below (Figure 1). The inner diameter of the pulley is 60.0
cm , while the outer diameter is 1.00 m . The system is released
from rest, and there is no friction at the axle of the pulley.
a) Find the acceleration of the stone.
b) Find the tension in the wire.
c)...

A weight with mass mw=150 gmw=150 g is tied to a piece of thread
wrapped around a spool, which is suspended in such a way that it
can rotate freely. When the weight is released, it accelerates
toward the floor as the thread unwinds.
Assume that the spool can be treated as a uniform solid cylinder
of radius R=4.00 cmR=4.00 cm and mass Ms=100 gMs=100 g . Find the
magnitude aa of the acceleration of the weight as it descends....

A 12.0-kg box resting on a horizontal, frictionless surface is
attached to a 5.00-kg weight by a thin, light wire that passes
without slippage over a frictionless pulley (the figure (Figure
1)). The pulley has the shape of a uniform solid disk of mass 2.20
kg and diameter 0.520 m .After the system is released, find the
horizontal tension in the wire.After the system is released, find
the vertical tension in the wire.After the system is released, find
the acceleration...

A light, nonstretching cable is wrapped around a solid cylinder
with mass 88 kg and radius 0.19 m. The cylinder rotates with
negligible friction about a stationary horizontal axis. We attach
the free end of the cable to a block of mass 48 kg, and release the
block from rest at a distance 3.9 m above the floor. As the block
falls, the cable unwinds without stretching or slipping. Find the
angular speed of the cylinder (in radians/s) the moment...

A 12.0-kg box resting on a horizontal, frictionless surface is
attached to a 5.00-kg weight by a thin, light wire that passes
without slippage over a frictionless pulley (the figure (Figure 1)
). The pulley has the shape of a uniform solid disk of mass 2.00 kg
and diameter 0.520 m .
Part A
After the system is released, find the horizontal tension in the
wire.
Part B
After the system is released, find the vertical tension in the
wire....
