Question
Problem Set 6 (Rotational Kinetic Energy)
A metal block with mass m= 7.50 kg is connected by a cord
wrapped around a 1.25-kg hollow cylinder pulley with a
frictionless axle as shown. The surface of the incline has a
coefficient of friction Hk = 0.30. As the block slides down
the inclined plane from rest at an angle of 35°, it pulls the
cord and causes the pulley to rotate. If the inclined plane
has a length of 2.25 m, calculate the speed v of the block
before it reaches the bottom. The pulley has a moment of
inertia of a solid disk, I =
mr?
and a radius r = 0.25 m.
