Alarge bell is hung from a wooden beam so it can swing back and forth with negligible friction. the center of mass of the bell is 0.50 m below the pivot, the bell has mass 32.0 kg , and the moment of inertia of the bell about an axis at the pivot is 20.0 kg⋅m2 . the clapper is a small, 1.8 kg mass attached to one end of a slender rod that has length l and negligible mass. the other end of the rod is attached to the inside of the bell so it can swing freely about the same axis as the bel

I'm kinda lost ! 1. when marilyn takes her pet dog for a walk, the dog walks at a veryconsistent pace of 0.55 m/s. draw a position-time graph to representmarilyn's dog walking the 19.8 m distance from the front of her house tothe nearest fire hydrant.2. both car a and car bleave school when a stopwatch reads zero. car atravels at a constant 75 km/h, and car b travels at a constant 85 km/h.a) draw a position-time graph showing the motion of both cars. howfar are the two cars from school when the stopwatch reads 2 hrs? calculate the distances and show them on your graph.b) both cars passed a gas station 120 km from the school. when dideach car pass the gas station? calculate the times and show themon your graph.3. the figure below shows the position-time graph showing a shopper'smovement up and down the aisle at a store.a) write a story describing the shopper's movements at the store.b) when does the shopper have a position of 6 m? c) how much time passes between when the shopper enters the aisleand when he gets to a position of 12 m? what is the shopper's averagevelocity between 37 s and 46 s?
