A daring stunt woman sitting on a tree limb wishes to drop vertically onto a horse gallop- ing under the tree. The constant speed of the horse is 6.2 m/s, and the woman is initially 2 m above the level of the saddle. How long is she in the air? The accelerationWhat is its initial vertical speed? The ac- celeration of gravity is 9.8 m/s2 and maximum height is 6.2 m ,. Neglect air resistance.
Answer in units of m/s.

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
