A spool of wire of mass m250 g and radius r45 cm is unwound, Ask an Expert

Academics

A spool of wire of mass M=250 g and radius R=45 cm is unwound under a constant force F = 5.0 N. Assume that the spool is a uniform solid cylinder that does not slip.

a) Determine the acceleration of the center of mass.

b) Determine the magnitude and direction of the force of friction.

c) If the cylinder starts from rest and rolls without slipping, what is the speed of its center of mass after it has rolled through a distance d? (Use any variable or symbol stated above as necessary).
