Question

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.)

Explanation / Answer

L = m*2*R*v*cos(0.5*w*t)


w --> angular frequency
