    • A car's brakes fail while driving down a mountain, and the car begins accelerating at 1.25 m/sec2. If the car travels 180.0 meters over the next 10.0 seconds, how fast was the car moving before its brakes failed?

Activities

    • Check answers on practice (pages 53, 55, and 58)

    • Class gravity lab

      • Purpose: to determine the characteristics of the motion of a falling object

      • Background: write as much of this as you can before class. Should include necessary equations, derivations of equations, safety comments, notes about procedure that will reduce uncertainty, assumptions, and how you'll make each measurement.
