2. What is the kinetic energy at time 3 seconds? 3. A pendulum of length .250 m is thermally expanded to .255 m. What is the original period of the pendulum and the final period of the pendulum? 4. How many hours will the initial length pendulum be behind a pendulum clock if that pendulum clock has a period of one second after 100 days?
1. A spring has a spring constant of 9 and a mass of 10 kg is attached. a. If it pulled back to 3 m, what is the kinetic energy of the spring mass half way to the equilibrium point? 2.
