Question

When a washing machine spins 6 kg ofclothes, they stick against the walls of the cylinder, inside the machine. The cylinder has an inner radius of 10 cm and an outer radius of 30 cm. Find the angular momentum of the cylinder when it has an angular veloci- ty of 1250 rad/s.​

Answer 1

Ответ:

1884,9 m²*kg/s

Объяснение:

R₁=10 cm

R₂=30 cm

Rc=(10+30)/2=20 cm=0,2 m

m=6 kg

n=1250 rad/s

M   ?   M =I*ω=m*Rc²*2*π*n=6*0,2²*2*π*1250=1884,9 m²*kg/s
