Question

Two gerbils run in place with a linear speed of 0.45 m/s on an exercise wheel that is shaped like a hoop.

Part A

Find the angular momentum of the system if each gerbil has a mass of 0.22 kg and the exercise wheel has a radius of 6 cm and a mass of 6.0 g .

Express your answer using two significant figures.

L =

_______

kg⋅m2/s

Answer 1

Here,

mass of the bat is m, Find the angular momentum of the system if each gerbil has a mass of 0.22 kg and the exercise wheel has a radius of 6 cm and a mass of 6.0 g .

here , for the total angular momentum of the system

as the gerbill's are not moving their angular momentum is Zero

moment of inertia of wheel , I = 0.006 * 0.06^2

I = 2.16 *10^-5 Kg.m^2

angular momentum = I * w

angular momentum = 2.16 *10^-5 * (0.45/.06)

angular momentum = 0.000162 Kg.m^2/s

the angular momentum of the system is 0.000162 Kg.m^2/s
