Two blocks (m1=5.5kg, m2=7.2kg
) are connected by a string that passes through a massless pulley
as shown in the Figure. The first block with mass
m1 slides up the inclined
plane when the system is released. The inclined plane makes an
angle θ = 310 with the
horizontal and the kinetic friction coefficient between the
inclined plane and m1 is
=0.35. Take g=10m/s2 Find
the speed of the block with mass m2 after it travels
h=5.6m.

Two blocks with masses m1 = 1.10 kg and m2 = 3.50 kg are
connected by a massless string. They are released from rest. The
coefficent of kinetic friction between the upper block and the

is frictionless, and calculate the speed of the blocks after they
have moved a distance 68.0 cm.

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

coming...

Objects with masses m1 = 12.0 kg and

An Atwood's machine consists of two masses, m1 and m2, connected
by a string that passes over a pulley. If the pulley is a disk of
radius R and mass M, find the acceleration of the masses.
Express your answer in terms of the variables m1, m2, R,
M, and appropriate constants.

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...
