A proton accelerates from rest in a uniform electric field of 524 N/C. At some later time, its speed is 2.36 × 106 m/s. What is the magnitude of the acceleration of the proton? The fundamental charge is 1.602 × 10?19 C. Answer in units of m/s2 013 (part 2 of 4) 6.0 points How long does it take the proton to reach this speed? Answer in units of ?s 014 (part 3 of 4) 6.0 points How far has it moved in this time interval? Answer in units of m 015 (part 4 of 4) 6.0 points What is its kinetic energy at the later time?
