how do I solve for angular momentum if the weight its 700 g and the angular v is (1m=r, 120rmp). I get 12.56 for the v. But i don't know how to solve for the monentum. Also is my v correct?
To solve for angular momentum, you need to know the moment of inertia (I) and the angular velocity (ω).
The formula for angular momentum (L) is given by:
L = I * ω
In your case, you have provided the weight (mass) of the object, which is 700 g. To obtain the moment of inertia, you need to know the shape and dimensions of the object. The moment of inertia varies depending on the shape, so without that information, it is not possible to calculate the angular momentum accurately.
As for your calculation of the angular velocity (ω), you mentioned that the angular velocity is given by 1 m = r and 120 rpm. However, there seems to be a confusion as 1 m is a distance, not a symbolic representation of radius (r). Without proper clarification, it is difficult to determine the correct value of ω.
In summary, you need to know the moment of inertia to calculate the angular momentum accurately. Additionally, you need to clarify the representation of the angular velocity (ω) before proceeding with the calculation.
