vf=vi+2ad
vf=0; vi=given; d=.2 solve for a.
A proton initially moves left to right long the x axis at a speed of 2.00 ´ 103 m/s. It moves into an
electric field, which points in the negative x direction, and travels a distance of 0.200 m before coming
to rest. What acceleration magnitude does the proton experience?
