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 = 36.5°.
The objects are released from rest, and
m2
slides 1.65 m down the slope of the incline
in 3.40 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.
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.
