The soap-box car has a weight of 110 lb, including the passenger but excluding its four wheels. Each wheel has a weight of 5 lb, radius of .5 ft, and a radius of gyration k = .3 ft, computed about an axis passing through the wheels axle. Determine the cars speed after it has traveled 100 ft starting from rest. the wheels roll without slipping. Neglect Air.
T1 = [tex]\sum[/tex]U1-2 = T2
The Attempt at a Solution
T1 = 0 because it starts from rest
for T2 the mass would be 110lb car pluss the 4 5lb wheels, converted to slugs of course, and the v is what i am looking for
im not sure about the middle term
I = mk3 = .1554*.32 = .013986
What else do i need
