(25%) Problem 2: An electron (m = 9.109 × 1031 kg) is in the presence of a constant electric field E. The electron has a charge of e = 1.602 × 10-19 C and it accelerates at a rate of a = 1900 m/s2. 33% Part (a) Write an expression for the magnitude of the electric field 33% Part (b) What is the field, in units of N/C? 33% Part (c) Assuming the electron begins at rest, what is its velocity after 0.55 s?

Explanation / Answer

initial velocity vo = 0

acceleration a = 1900 m/s^2

time interval t = 0.55 s

v = vo + a*t

v = 0 + (1900*0.05)

v = 95 m/s <<<-----ANSWER
