Two masses are connected by a massless string, passing over a
massless, frictionless pulley as shown in the diagram. Mass
m1 = 5 kg, and is released from rest at a
height h = 4 m above the table. Mass
m2 = 3 kg, and starts at rest on the table.
Ignore friction and air resistance. Take the system to be the two
masses and the earth. What is the potential energy of this system,
in Joules? Next, you let...

Two masses M1 and M2 are connected by an inextensible
flexible massless string. The mass rests on a table with frictional
co-efficient 0.2. The string passes over a smooth fixed pulley as
shown. Initially the string is slack The mass M2 is allowed to fall
freely from rest. The string becomes taught when the mass M2 falls
through 50 cm. The two masses subsequently move with common
velocity. Determine how far mass M1 will travel on the table before
coming...

Two
blocks of masses of 2.00 kg and 4.00 kg are connected by a massless
string going over a smooth, massless pulley. The table on which the
smaller mass rest is frictionless. The other side of the 2.00 kg
mass is connected to a spring of k=250 N/m and the far end of the
spring is tied to a fixed point. The system is release from rest
with the spring at its relaxed length.

A system comprises two objects, a massless string, a
frictionless (but not massless) pulley and the Earth. The objects,
1 and 2, have masses of 0.111 and 0.316 kg, respectively, and hang
from opposite ends of the string, which is draped over the pulley.
The pulley has a radius of 0.100 m. Initially, you are holding
Object 1 to keep the system from moving. Then you let go, allowing
the objects to move a vertical distance of 1.00 m and...

Two masses, m1 and m2 hang over a frictionless pulley by means
of a massless string. They are perfectly balanced when a flea of
mass m3 is standing on m2. When the flea hops from one mass to the
other, the system acquires an acceleration, a. What is the value of
the flea's mass, m3 in terms of two masses, m1 and m2, and the
acceleration, a? (a) what is m3 in terms of m1 and m2? (b) what is...

Two blocks are connected by a string that passes over a
massless, frictionless pulley, as shown in the figure. Block A,
with a mass mA = 2.00 kg, rests on a ramp
measuring 3.0 m vertically and 4.0 m horizontally. Block B hangs
vertically below the pulley. Note that you can solve this exercise
entirely using forces and the constant-acceleration equations, but
see if you can apply energy ideas instead. Use g = 10
m/s2. When the system is released...

Two masses are connected by a string that passes over a pulley.
The mass m1 is 9.2 kg, and the mass m2 is 1.6
kg. When the masses are simultaneously released from rest, what is
the magnitude of their acceleration (in m/s2)? Neglect
any friction.
[Note: if you need to enter a number in scientific notation, use
'e'. For example, 1200 = 1.2e3 and 0.0012 = 1.2e-3. Include several
decimal places in your calculations and your answer to avoid
rounding...

Two masses are tied together with a string and swung at a
constant speed in a horizontal circle. The inner string
(connecting the center to the first mass) has a length of 72.0 cm
and the outer string (connecting the first mass to the second mass)
has a length of 45.0 cm. The inner object has a mass of
m1= 540 g, the outer object has a mass of
m2=360 g. The balls complete 5 rotations in 6.4
s. Find...

Two blocks with masses M1 and M2 are connected by a massless
string that passes over a massless pulley as shown. M1 has a mass
of 2.25 kg and is on an incline of 49.5° with coefficient of
kinetic friction ?1 = 0.205. M2 has a mass of 5.45 kg and is on an
incline of 31.5° with coefficient of kinetic friction ?2 = 0.105.
Find the magnitude of the acceleration of M2 down the incline.

Two masses M1=2kg and M2 are attached by a massless cord over a
solid pulley wheel of mass M=4kg, and radius R=5cm. Static Friction
between the cord and the pulley makes the pulley rotate
counter-clockwise when the system is released from rest, M1
accelerates with a magnitude of 3.92 m/s2 .
a) Draw and label the forces acting on the two blocks, and the
pulley. (6 points)
b) Find the tension in the cord between the pulley and M1 (6...
