Homework Help: physics

Posted by Anonymous on Thursday, January 10, 2013 at 7:34pm.

A toy top consists of a rod with a diameter of 13.00 mm and a disk of mass 0.0160 kg and a diameter of 3.5 cm. The moment of inertia of the rod can be neglected. The top is spun by wrapping a string around the rod and pulling it with a velocity that increases from zero to 3.0 m/s over 0.40 s.

a) what is the resulting angular velocity in rad/s?


b) what is the force exerted on the string in newtons?
