Question
Compute the linear momentum and angular momentum of a Frisbee of mass 0.175 kg if it has a linear speed of 1.65 m/s and an angular velocity of 61.5 rad/s. Treat the Frisbee as a uniform disk of radius 12.0 cm.

Linear momentum
p=mv=0.175•1.65=0.289 kg•m/s
Angular momentum
L=I•ω=(mr^2/2) •ω=(0.175•(0.12)^2/2) •61.5=77.5 kg•m^2/s
p=mv=0.175•1.65=0.289 kg•m/s
Angular momentum
L=I•ω=(mr^2/2) •ω=(0.175•(0.12)^2/2) •61.5=77.5 kg•m^2/s
