1. A box is attached to a horizontal spring and compressed 0.2 meters. The spring constant is 20 N/m. What is the force from the spring once the spring is compressed? a. -4 N b. -100 N c. -40 N d. 100 N 2. A ball of mass 2 kg is attached to a vertical spring. The ball displaces 0.1 m once it is attached. What is the spring constant? a. 196 N/m b. 19.6 N/m c. 20 N/m d. 0:2 N/m 3. A ball is attached to a vertical spring of 200 N/m spring constant. The ball moves downward 0.5 meters. What is the mass of the ball? a. 40 kg b. 10 kg c. 100 kg d. 400 kg 4. If you double the amplitude of a box on a spring, how would that affect the acceleration at maximum displacement? a. The acceleration would double. b. The acceleration would be cut in 1/2. c. The acceleration would remain the same. d. The acceleration would triple. 5. A mass on a spring is first placed on a table ans set in SHM and then held vertically and set in SHM. What variables would change between the two scenarios? Select all that apply. a. The equilibrium position b. The period of oscillation c. The spring force at equilibrium d. The spring constant 6. A pendulum of 1-meter length is pulled back 0.05 meters and released so that it undergoes simple harmonic motion. If you were to repeat that experiment, but instead, pull the pendulum back 0.1 meters, how would this affect the period compared to the 0.05-meter pull? a. The period would increase. b. The period would remain the same. c. The period would double. d. The period would decrease
