Q1. When you see a traffic light turn red 20 m from you, you apply brakes (assume you have zero reaction time) until you come to a stop exactly at the line of the traffic light. If your initial speed was 10 m/s and you were heading due north, calculate the time elapsed while your car comes to a stop? Suppose constant deceleration.

Q2. A pendulum of length 1.5 m is held out to point A. At the vertical position, an overhang effectively cuts the length of the pendulum by an amount equal to 1.09 m. (That is, 1.0 m is no longer free to swing.) How long does this pendulum take for one oscillation? Suppose that all displacement angles are small.
