This question has two correct answers. Both must be answered correctly to earn credit. On the Earth a mass is attached to a vertical spring. The mass is held upwards so that the spring is unstretched and then released. Another mass is attached to a string to make a pendulum. The pendulum is pulled over 10° and released. If the spring oscillator and the pendulum were taking to the Moon and set in motion in the same way as before, which of the following would change? A) The spring oscillator's period.

The block, initially at rest on a frictionless, horizontal surface, is connected to a spring with force constant 900 N/m. The block moves d = 5.00 cm to the right after impact before being brought to rest by the spring.

An internal part recoils over a relatively large distance and is stopped by damping mechanisms in the gun. The larger distance reduces the average force needed to stop the internal part.
