To solve the problem, we start with the given acceleration of a particle traveling along a straight line, which is defined as: a=kv wherekis a constant andvis the velocity of the particle. We know that accelera
题目A particle moves along the x-axis so that at any time t≥q 0 the acceleration of the particle is a(t)=e^(-2t). If at t=0 the velocity of the particle is 52 and its position is (17)4, then its position at any time t>0 is x(t)= ...
A particle moves in the x-y plane with a constant acceleration ofin the direction making an angle ofwith the x-axis. At t=0 the particle is at the origin and its velocity is 8.0m/s along the x- aixs . Find the velocity and the position of the particle at t = 4.0s. ...
It is shown by calculation that conditions in solar proton flares are such that the charged particles can be effectively accelerated to tens of MeV, even ~1 GeV. It is shown that the combined acceleration by a regular electric field and ion-acoustic turbulence pumps the protons and other ...
