Correct answer and explanation please.

5. [-/14.28 Points] DETAILS SERCP9 15.P.020.WI.SOLN. An electron is accelerated by a constant electric field of magnitude 300 N/C. (a) Find the acceleration of the electron. m/s 2 (b) Use the equations of motion with constant acceleration to find the electron's speed after 1. 25 x 10 assu it starts from rest. m/s 6. [-/14.28 Points] DETAILS SERCP9 15.P.023.MI.FB. A proton accelerates from rest in a uniform electric field of 648 N/C: At some later time, its speed (a) Find the magnitude of the acceleration of the proton m/s2 (b) How long does it take the proton to reach this speed? US (c) How far has it moved in that interval? E (d) What is its kinetic energy at the later time? Need Help? Master It
