Homework Help: Help with this proof

  1. Oct 3, 2005 #1
    the question asks consider a particle of mass m whose motion starts from rest in a constant gravitational field. if a resting force proportional to the square of the velocity (i.e, kmv^2) is encountered, show that the distance s the particle falls from vnot to v1 is given by

    s(vnot-> v1)= 1/2 [(g-kvnot^2)/(g-kv12}]

    I hate proofs :eek:

    Are you supposed to use differential equations to solve this?
