1. The problem statement, all variables and given/known data

Consider a particle of rest mass m0 subjected to a constant force F. The particle starts at rest; then at time t>0, the constant force F is applied. Calculate the particle's velocity v as a function of time t for times t>0. HINT: first calculate the particle's momentum as a function of time (easy!), then figure out its velocity v(t).

2. Relevant equations

F=dp/dt
p=Y*m0*v


3. The attempt at a solution

I used F=d(Y*m0*v)/dt and tried to solve it for v, but ended up doing a lot of algebra (which wasn't supposed to happen, apparently) and my equations lacked a variable, t.

Help?
