A spaceship of mass 2.30×106 kg is cruising at a speed of 5.20×106 m/s when the antimatter reactor fails, blowing the ship into three pieces. One section, having a mass of 4.90×105 kg, is blown straight backward with a speed of 2.20×106 m/s. A second piece, with mass 8.20×105 kg, continues forward at 1.30×106 m/s. What is the speed of the third piece?

Anybody wanna ? (picture included? )

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
