Space out the questions below to accommodate your answers and then save and submit this file as your lab. pdf versions of the file are preferred, although this is not strictly required. just be sure to submit a file that is of a commonly used format.
question 1:
make the following changes to the simulation program:
1. set the simulation to "1 dimension".
2. un-check "center of mass" and "reflecting border".
3. move the sliders so that each mass reads 1.5 kg.
4. click on the "more data" button.
now! we begin by simply observing the default collision in the simulation. look at the data table. it tells me that the two balls have the same mass and also that their velocities are different. the velocities are labeled òvxó. calculate the total momentum of these two balls and show your work below including units where appropriate. (hint: object 2 is travelling in the negative direction and therefore has negative momentum.

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.

Point charges q1 = 51 µc and q2 = −27 µc are placed 1.0 m apart, with q2 on the right. what is the force (in n) on a third charge q3 = 19 µc placed midway between q1 and q2? (assume the positive direction is to the right. indicate the direction with the sign of your answer.)
