P 4 . 6 In Figure 4 . 6 5 , two rollers are attached to the ends of a thin plate, which are constrained to roll within two stationary channels. Model the rollers as particles. The mass of the plate is 1 3 k g . The lower wheel is moving leftward with a veloc - ity v = 0 . 1 m s . Find the plate's lin - ear momentum and the angular momen - tum about its mass center at the config - uration shown in Figure 4 . 6 5 . ( answer: the magnitude of the linear momentum is 0 . 7 2 k g m s and the magnitude of the angu - lar momentum is 0 . 9 2 k g m 2 s . ) Figure 4 . 6 5 : Thin Plate and Rollers
