A 1840 kg car has just passed a diner. The closest the car came to the diner was R = 32.5 m, but the car has driven another x = 40.7 m in the 2.05 s elapsed since then. If the car travels at constant speed, what is the current magnitude of the angular momentum of the car about the diner?

The figure shows a rigid structure consisting of a circular hoop of radius R and mass m1 and a square made of four thin bars, each of length R and mass m. The rigid structure rotates at a constant speed about a vertical axis, with a period of rotation of s. If R = m and m = kg, calculate the angular momentum about that axis. At the instant of the figure, a kg particle P has a position vector...
