A proton moves with a speed of 8.0\times 10^6 mls along the +x -axis. It enters a region where there is a magnetic field of 5.0
T, directed at an angle of 60° to the horizontal axis. The charge
of the proton is 1.6\times 10^{-19}\C.*

You notice a very one-dimensional-thinking snail crawling along one rail of a railroad track. naturally, you remove it to a safer place. but before you do, you observe it as it moves from position xi = -92.9 cm to position xf = -64.9 cm along the rail, as measured from a point where one rail abuts the next. what is the snail\'s displacement δx in centimeters?
