Question

Objects of masses m1 = 4.00 kg and m2 = 9.00 kg are connected
by a light string that passes over a frictionless pulley as in the
figure below. The object m1 is held at rest on the floor, and

m2 rests on a fixed incline of θ = 37.5°. The objects are
released from rest, and m2 slides 1.10 m down the slope of the
incline in 4.45 s.

A triangular structure is oriented such that its base rests
upon a horizontal surface, its left side is perpendicular to its
base, and its right side forms an incline of angle θ. A pulley is
attached to the structure's apex. Two objects are connected by a
cord that passes over the pulley.

An object labeled m1 is attached to the left end of the cord
and hangs such that it is very close to the horizontal
surface.

A rectangular object labeled m2 is attached to the end of the
cord and rests upon the incline.

A pale image of m1 is above m1, and a pale image of m2 is
farther down the incline than m2.

(a) Determine the acceleration of each object. (Enter the
magnitude only.)

m/s2

(b) Determine the tension in the string. (Enter the magnitude
only.)

N

(c) Determine the coefficient of kinetic friction
between

m2

and the incline.

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 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...

A m1 = 13.5 kg object and a
m2 = 10.0 kg object are suspended, joined by a
cord that passes over a pulley with a radius of 10.0 cm and a mass
of 3.00 kg (Fig. P10.46). The cord has a negligible mass and does
not slip on the pulley. The pulley rotates on its axis without
friction. The objects start from rest 3.00 m apart. Treating the
pulley as a uniform disk,determine the speeds of the two objects...
