A proton has an initial velocity of 4.50 x 10^5 m/s in the horizontal direction. It enters a uniform electirc field of 9.60 N/C directed vertically. Find
a) the time it takes the proton to travel 5.00 cm horizontally.
b) the vertical displacement of the proton during the this time.
c) the horizontal and vertical components of the proton's velocity at the end of this time.
