Task 1.5.2: Inquiry - deriving the Big '5' Practice 5: Given the same skater as in Practice 4 (starting from rest, and accelerating down at 2m/s? [D]) b) How much displacement is covered between 15s and 20s of travel? Givens: Write info given Required: What's needed? Analysis: Sketch a motion graph Is it easier to use the graph? Just need a slope? 1 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
