A light, rigid rod l = 8.04 m in length rotates in the xy plane about a pivot through the rod’s center. Two particles of masses m1 = 8.9 kg and m2 = 3.5 kg are connected to its ends. x y l v v m2 m1 Determine the angular momentum of the system about the origin at the instant the speed of each particle is v = 3.65 m/s. Answer in units of kg m2 /s.

Students design a model roller-coaster track. they place a rubber ball at the highest point on the track and let it go. the ball rolls along the track pulled only by the force of gravity. eventually, it comes to a stop. which change to the design will result in the ball moving the greatest distance?
