A proton is projected in the positive x direction into a region of uniform electric field Earrowbold = (-5.40 multiplied by 105) i hat bold N/C at t = 0. The proton travels 6.20 cm as it comes to rest.
(a) Determine the acceleration of the proton.
(b) Determine the initial speed of the proton.
(c) Determine the time interval over which the proton comes to rest.
