1. A golf ball rolls up a hill towards a miniature-golf hole. Assume that the direction toward the hole is positive.
a. If the golf ball starts with a speed of 2.0 m/s and slows at a constant rate of 0.50
m/s, what is the velocity after 2.0 s?
b.
What is the golf ball's velocity if the constant acceleration continues for 6.0 s?

Along the line connecting the two charges, at what distance from the charge q1 is the total electric field from the two charges zero? express your answer in terms of some or all of the variables s, q1, q2 and k =14ï€ïµ0. if your answer is difficult to enter, consider simplifying it, as it can be made relatively simple with some work.
