Figure 10.19 shows a rotating food tray, often called a lazy Susan, being turned by a person

Question:

Figure 10.19 shows a rotating food tray, often called a lazy Susan, being turned by a person in quest of sustenance. Suppose the person exerts a 2.50 N force perpendicular to the lazy Susan’s 0.260-m radius for 0.150 s.

(a) What is the final angular momentum of the lazy Susan if it starts from rest, assuming friction is negligible?

(b) What is the final angular velocity of the lazy Susan, given that its mass is 4.00 kg and assuming its moment of inertia is that of a disk?
