1. The problem statement, all variables and given/known data Starting from the modified Newton's Law (dp(rel))/dt=F with a constant Force F, and assuming that the particle starts with v=0 at time t=0, show that the velocity at time t is given by V(t)=c [(Ft/mc)/(1+ Ft/mc)] 2. Relevant equations 3. The attempt at a solution I know that I can integrate both sides of the equation with respect to time and solve, but i'm stuck on how to start that off. Any help would be appreciated!
