Can you suggest me please how to set my equations in order to get the angular momentum in this problem?
A particle of mass m moves in a circle of radius R at a constant speed v, as shown below. The motion begins at point Q at time t = 0. Determine the angular momentum of the particle about the axis perpendicular to the page through point P as a function of time. (Use any variable or symbol stated above along with the following as necessary: t.)
I have the answer, but I have no idea how to get it,
Since the angular momentum is m times the cross product of radius and velocity, I tried to set the y and x coordinates of these two vectors but I think I miss something in the velocity vector
