Task 1.5.2: Inquiry - deriving the Big '5' Practice 2: A car with an initial velocity of 10 m/s [E] decelerates at 5.0 m/s? [W] until stopped. How much time long does this take? 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 7 / 10 +
