an electrically charged particle accelerates uniformly rom rest to speed v while traveling a distance x. a)show that the acceleration of the particle is a = v2/2x. b)if the particle starts from rest and reaches a speed of 1.8 x 10^7 m/s over a distance of 0.10m, show that its acceleration is 1.6 x10^15 m/s2
