A uniform flat disk of radius R and mass 2M is pivoted at point P. A point mass of 1/2 M is attached to the edge of the disk. Calculate the moment of inertia ICM of the disk (without the point mass) with respect to the central axis of the disk, in terms of M and R.
Calculate the moment of inertia IP of the disk (without the point mass) with respect to point P, in terms of M and R.
Calculate the total moment of inertia IT of the disk with the point mass with respect to point P, in terms of M and R.

There was no intial y-momentum so the net final y-momentum must also be 0. they can have final velocities in the y-direction

Hello @mmmhhbhb,how are you doing? i will answer each question individually below! i hope it ! remember to contact me if you need further assistance!   1. what is the wave speed of a wave that has a frequency of 100 hz and a wavelength of 0.30 m? 100 hz x .30 m = 30 m/s2. what is the wave speed of a wave that has a frequency of 50 hz and a wavelength of 0.10 m? 50 hz x .10 m = 5 m/s3. what is the frequency of a wave that has a wave speed of 20 m/s and a wavelength of 0.50 m? 20 m/s divided by .50 m = 40 hz4. what is the frequency of a wave that has a wave speed of 80 m/s and a wavelength of 0.20 m? 80 m/s   divided by .20 m = 400 hz5. what is the frequency of a wave that has a wave speed of 120 m/s and a wavelength of 0.40 m? 120 m/s divided by .40 m = 300 hz6. what is the wavelength of a sound wave that has a speed of 340 m/s and a frequency of 440 hz? 340 m/s divided by 440 hz = .77 m7. what is the wavelength of a sound wave that has a speed of 340 m/s and a frequency of 880 hz? 340 m/s divided by 880 hz = .38 m8. what is the wavelength of a sound wave that has a speed of 250 m/s and a frequency of 400 hz? 250 m/s divided by 400 hz = .63 m9. what is the wave speed of a wave that has a frequency of 50 hz and a wavelength of 2.0 m? 50 hz x 2.0 m = 100 m/s10. what is the wave speed of a wave that has a frequency of 100 hz and a wavelength of 0.50 m? 100 hz x 0.5 m = 50 m/sthat's all, hope i !   you,  darian d.
