Question

A 1.5 kg block and a 2.7 kg block are attached to opposite ends of a light rope. The rope hangs over a solid, frictionless pulley that is 28 cm in diameter and has a mass of 0.80 kg .

When the blocks are released what is the acceleration of the lighter block? Express your answer in meters per second squared

Answer #1

A block of mass 18 kg and a block of mass 6 kg are attached by a
massless string that does not stretch. The string is passed over a
massless, frictionless pulley. The blocks are released. The blocks
slide against vertical walls as they move, which results in a
frictional force of 25N acting on the heavier block and a
frictional force of 14N acting on the lighter block.
(a) Determine the magnitude of the acceleration of each
block.

Two blocks are attached to opposite ends of a string that passes
over a massless, frictionless pulley (see the figure). Block ? of
mass 10.0 kg lies on a 60.0° incline with a coefficient of friction
of 0.500, and block ? of mass 1.00 kg is attached to a vertical
spring of force constant 200 N/m. The blocks are initially at rest
with the spring at equilibrium. Find the maximum height that the
block ? rises.

Block A, mass 5.00 kg, rests on a surface with μk = 0.600. A
massless rope is attached to its right side, and runs over a
pulley, treated as a thin ring, mass 1.00 kg and radius 5.00 cm, to
Block B, mass 7.00 kg, which hangs from the rope and is held at
rest. The rope does not slip over the pulley, and the pulley spins
on a frictionless axle. Block B is released from rest, and after an...

A 4.00 kg block hangs by a light string that passes over a
massless, frictionless pulley and is connected to a 6.00 kg block
that rests on a frictionless shelf. The 6.00 kg block is pushed
agaisnt a spring to which it is not attached. THe spring has a
spring constant of 180 N/m , and it is compressed by 30.0cm. Find
the speed of the block after the spring is released and the 4.00 kg
block has fallen a...

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 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 2.10-kg frictionless block is attached to an ideal spring with
force constant 355 N/mN/m. Initially the spring is neither
stretched nor compressed, but the block is moving in the negative
direction at 15.0 m/s
A)Find the maximum acceleration of the block.
Express your answer in meters per second squared.
B)Find the maximum force the spring exerts on the block.
Express your answer in newtons.

A block with mass m1 hangs from a rope that is extended over an
ideal pulley and attached to a second block with mass m2 that sits
on a ledge. The second block is also connected to a third block
with mass m3 by a second rope that hangs over a second ideal pulley
as shown in the figure below. If the friction between the ledge and
the second block is negligible, m1 = 2.60 kg, m2 = 4.00 kg,...

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....

Two blocks with different mass are attached to either end of a
light rope that passes over a light, frictionless pulley that is
suspended from the ceiling. The masses are released from rest, and
the more massive one starts to descend. After this block has
descended 1.19 m, its speed is 3.18 m/s. If the total mass of the
two blocks is 14.5 kg, what is the mass of each block? (Enter your
answers from smallest to largest.
