Q1. David is driving a steady 27m/s when he passes Tina, who is sitting in her car at rest. Tina begins to accelerate at a steady 2.20m/s^2 at the instant when David passes.
A) How far does Tina drive before passing David?
B) What is her speed as she passes him?
Q2. A stand, string, a paper or plastic cup, a nail, a roll of paper towels or similar sized paper, coloured sand, or some other dry powdery product, and a ruler or measuring tape.
Following the procedure in the video, create three traces of the pendulum motion of the cup. Compare the three traces for amplitude, wavelength, and frequency. Create three traces of the pendulum motion of the cup. Compare the three traces for amplitude, wavelength, and frequency.
