John McClane, desperately trying to escape the bad guys in an upper floor of a skyscraper, grabs a fire hose and crashes out a window. He falls toward the ground, dragging the hose with him. The hose is wound around a cylinder that has a moment of inertia equal to 5 kg m2, and the hose unspools from the cylinder as McClane falls.

John McClane, desperately trying to escape the bad guys in an upper floor of a
skyscraper, grabs a fire hose and crashes out a window. He falls toward the ground,
dragging the hose with him. The hose is wound around a cylinder that has a moment of
inertia equal to 5 kg
m2, and the hose unspools from the cylinder as McClane falls. Assuming that the hose is
pulled from the cylinder at an angle that is perpendicular to the cylinder's radius, what is
McClane's acceleration? Let McClane's mass be 75 kg and the radius of the cylinder be
0.5 m. Neglect friction and air resistance.
