Part B Now check your hypothesis by investigating two Tracker videos: Ball Drop and Large Ball Drop.
Open the Tracker experimentBall Drop C. Watch the movie by clicking on the play button. (The other video controls allow you to "rewind" the
video or step forward or backward one frame at a time.). Watch the video to go ahead with the activity,
Now, keep the Ball Drop video open, and also open the Tracker experiment Large Ball Drop and watch that video.
For the Ball Drop experiment, observe the graph of the vertical displacement of the small ball against time (y vs. t). What can you say about the
vertical displacement of the small ball? What graph shape is this? What does this shape tell you about the mathematical relationship between y
and t?

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?
