Question

I can test a new wheel design by rolling it down a test ramp. I release a wheel of mass m=1.9 kg and radius r=0.37 m from rest at an initial height of h=5.1 m at the top of a test ramp. It smoothly rolls to the bottom without sliding. I measure the linear speed of the wheel at the bottom of the test ramp to be v=3.1 m/s. What is the rotational inertia of my wheel?

Select one:

2.45 kg m^2

1.47 kg m^2

2.69 kg m^2

2.93 kg m^2

1.96 kg m^2
