Task 1.5.2: Inquiry - deriving the Big '5' Practice 3: A golf ball rolls has a velocity of 25 m/s [fwd] and slows down at a rate of 5.0 m/s2 [bck]. Find its displacement after 15s. Givens: Write info given Required: What's needed? Analysis: Sketch a motion graph Is it easier to use the graph? Just need a slope? Just need an area? - Does the time interval not start at zero? Is it easier to use an equation? Only missing 1 variable? - Does the time interval start at 0? Solution: Solve using either the graph or the equation. Confirm with the other option Page 8 / 10
