It seems that there is missing information in the equation. Could you please provide the value for either the mass (m) or the velocity (v) in order to calculate the momentum (P)?
It seems like you have provided an incomplete equation. Could you please provide the missing information or clarify your question?
It seems like you have provided an incomplete equation. The equation you mentioned, "P=mv", is the formula for calculating momentum, where P represents momentum, m represents mass, and v represents velocity.
However, in your case, you have mentioned "45n" without an operator or equal sign. Could you please provide more information or clarify what you are looking for?
