A proton has an initial velocity of
1.76 × 107 m/s in the horizontal direction.
It enters a uniform electric field of 6300 N/C
directed vertically.
Ignoring gravitational effects, find the
time it takes the proton to travel 0.035 m
horizontally. The mass of the proton
is 1.6726 × 10−27 kg and the fundamental
charge is 1.602 × 10−19 C .

What is the proton’s speed after being in the
electric field for that time?
Answer in units of km/s
