Having aced her physics class, a student gets a cool summer job with NASA that involves playing golf on distant planets. For the first drive on the 4th hole on the planet Lgis, the total velocity of her ball is as plotted to the left. The ball lands at the same vertical level at which it starts. Along with being distant, the planet Lgis is airless, so we can ignore air resistance. 1) How far will her ball go horizontally before it strikes the ground on the first bounce? 2) What is the acceleration due to gravity on Lgis?
3) What is the maximum height the ball reaches above the surface?

To understand the electric potential and electric field of a point charge in three dimensions consider a positive point charge q, located at the origin of three-dimensional space. throughout this problem, use k in place of 14? ? 0. part adue to symmetry, the electric field of a point charge at the origin must point from the origin.answer in one word.part bfind e(r), the magnitude of the electric field at distance r from the point charge q.express your answer in terms of r, k, and q. part cfind v(r), the electric potential at distance rfrom the point charge q.express your answer in terms of r, k, and q part dwhich of the following is the correct relationship between the magnitude of a radial electric field and its associated electric potential ? more than one answer may be correct for the particular case of a point charge at the origin, but you should choose the correct general relationship. a)e(r)=dv(r)drb)e(r)=v(r)rc)e(r)=? dv(r)drd)e(r)=? v(r)r
