BASICOT POST DO NOT ASSIST DO NOT POST DO NOT ASSIST DO NOT POST DO NOT ASSIST For filming a physics demonstration about oscillation, an educational video crew attaches a large spring to a very small car's front bumper, puts the car in neutral, seats two actors inside, then gives the car a solid push to get it going. After that, the car rolls back and forth smoothly.

Calculate the spring's stiffness k. Don't forget the units! :) DO NOT POST DO NOT ASSIST (2) MVQ, RNG If an even number of people (including you) live in your household, pick an amplitude SSIST (maximum stretch, 3-5 m) for the spring's oscillation and calculate the car's maximum acceleration. NOT ASSIST Or (odd) choose the car's maximum acceleration (2-4 m/s) and calculate the amplitude of the oscillation. ASSIST DO NOT POST DO NOT ASSIST For either version of the quesion, start from N2L and show all steps. (3) RNG Pick an instant when the spring is stretched to 60-90% (3 SF) of the amplitude. For example, if in #2. A = 8.88 m, then 67.3% of that would be Ar = 0.6738.88 m = 5.98 m. Round your Ar to 3 SF, then calculate the car's speed v at this instant, total = E, Show all that the car's total mechanical energy is conserved: E = O NOT steps, including cancellations, suming that the car's total mech (4) The crew also sets up a large pendulum in the scene, hanging overhead and swinging back and forth in sync with the car. Calculate the pendulum's length. POST DO NOT ASSIST DO NOT POST DO NOT ASSIST (5) RNG One of the actors (mass m, 80-120 kg) steps out of the car in the middle the demo. Calculate the middle the demo. Calculate the car's original (f, both actors) and new (fnews one actor) oscillation frequencies. (6) Comparing and fnew, is the ride more smooth or more jerky than before for the actor remaining in the car? Explain in 1-2 sentences.
