Homework Statement
A 1.9 kg ball attached to a string whose length is 1.8 m moves counterclockwise (as viewed from above) in a horizontal circle (see figure below). The string makes an angle θ = 30° with the vertical.
(a) Determine both the horizontal and vertical components of the angular momentum of the ball about the point of support P. (Use variables w,t and directions i, j, and k as necessary.)
horizontal 1
vertical 2
(b) Find the magnitude of d/dt.
3 N*m
