Kurt owns a particle (6.0 g) that he shoots at 4.0 km/s into the xy plane, in a region with a nk uniform magnetic field given by 5.0 i mt. at one instant, he notices that when the particle's velocity is directed 37â° counterclockwise from the positive direction of the x axis, the magnetic force on the particle is 0.48 k n. k fo a. what is the particle's charge? definite your coordinate system and draw the details of the 2 right-hand rule that support your choice of positive or negative charge. the magnetic field? the directions must be clearly depicted in the diagram! particle's () radius, (i) cyclotron frequency, and (i) pitch in b. what will kurt measure for the c. draw a diagram that is a good representation of the helical trajectory of the particle.

a=d/t

a="triangle"v/t

explanation:

a = acceleration

russian is not my first language, so i'm afraid i can't write out an answer in russian, but hopefully you can find a way to do so. here's my best translation of the problem: you're given a plot of a particle's position in one-dimensional space over time, and you're asked to find either the total distance traveled by the particle after 6 seconds had elapsed, or the total displacement of the particle after 6 seconds.

if you want the total distance traveled, you would first need to determine the particle's velocity as a function of time, then integrate that over the 6-second interval. we know the position function is quadratic with roots at 0 and 6, so we have

where is unknown. because the position is parabolic, there is symmetry about the midpoint at , and we know that

so that the position function is

which means the velocity is

then the total distance traveled is

so the total distance traveled is 20 m.

on the other hand, if you want to find displacement: the particle starts at and ends at , so its displacement is 0.
