Couldn't find an option for submitting corrections, so I'm usingthis function instead...sorry. Although the answer is correct, thelast term of the problem has (0.030m)^2 where it should have(0.300m)^2. Please make sure that this is corrected.
Thanks

P.S. If this "question" is not automatically tagged, this is inreference to question 20 of chapter 21 in University Physics withModern Physics (12th Ed.) by Young and Freedman.

Hi, I bought a used "University Physics 12th Edition" textbook byYoung and Freedman, but the person I bought it from didn't have the"MasteringPhysics" access code - he suggested I ask here, becausethere might be a lot of people who have the access code and don'tneed it. So, does anyone have an access code for this?

Thanks

Problem is:-

A ball is thrown upwards with speed v0. The ball has net charge Qand travels in the presence of an electric field whose potentialfunction is U = (k/2) y2. Positive y is taken as vertically up. Donot neglect gravity.

a.) Compute the electric field components.
b.) Compute the net force on the ball.
c.) How high does the ball go?

Hint: Use energy conservation.
Note: Assume y0 = 0 and vy (0) = v0y.
(I'm using the university physics young and freedman 12th edition )
