2. (39) Two
masses are connected by a cable that is
wrapped around a pulley of moment of
inertia I and radius R = 1.0 m. The acceleration of the blocks has magnitude a = 0.020 m/s^{2}. No friction.
(a) (5) What is T_{2} ?
(b ) (5) What is T_{1} ?
(c ) (11) What is I?
(d) (5) If the pulley is in the shape of
a solid disk, then what is the mass M of the pulley?
(e) (3) Assume the system starts from
rest. What is the speed v of the blocks after 5.0 seconds?
(f) (6)
What is the magnitude L of the angular momentum of the
pulley after 5.0 seconds?
(g) (4) What is
the direction, in or out of
the page, of the angular
momentum of the pulley after 5.0 seconds of motion? Assume the
axis of rotation is perpendicular to the page.
(a) (16)What is
the tension T ?
(b) (6) What is
the horizontal component of force F_{h}
exerted on the beam by the wall ?
(c) (8) What is
the vertical component of force F_{v}
exerted on the beam by the wall ?
