The rube goldberg device included in the lab is, an example of a closed system because all of the matter (such as the string, the ball and the books) stayed in the area. however the potential energy, that was stored in the ball on the high shelf and suspended weights as well as the stored mechanical energy of the sling shot, had left the system in the form of sound, motion and heat. now, take a look at the device you created and explain what type of energy system (open, closed or isolated) is represented by the lab device and why?

Ajogger accelerates from rest to 4.86 m/s in 2.43 s. a car accelerates from 20.6 to 32.7 m/s also in 2.43 s. (a) find the magnitude of the acceleration of the jogger. (b) determine the magnitude of the acceleration of the car. (c) how much further does the car travel than the jogger during the 2.43 s?

Students in an introductory physics lab are performing an experiment with a parallel-plate capacitor made of two circular aluminum plates, each 11 cm in diameter, separated by 1.0 cm. how much charge can be added to each of the plates before a spark jumps between the two plates? for such flat electrodes, assume that value of 3×106n/c of the field causes a spark.
