A proton accelerates from rest in a uniform electric field of 600 N/C. At one later moment, its speed is 1.30 Mm/s (nonrelativistic because v is much less than the speed of light) (a) Find the acceleration of the proton 5.74e10m s2 (b) Over what time interval does the proton reach this speed? Your response is within 10% of the...

One possible worry about electric cars is that they're currently powered by dirty electricity. But proponents, as quoted in this story on the issue, claim that they're still cleaner than traditional cars even if their electricity comes from fossil fuels because of how efficient large-scale electricity production is and how efficient electric motors are. Let's investigate for ourselves. 1.) Let's...
